AC Milan's highly-rated young goalkeeper Gianluigi ​Donnarumma has put Europe's top clubs on alert after stalling on a new contract.

The 17-year-old has established himself in the Italian giants' first-team after making his breakthrough last season but with his contract running out in 2018, clubs including Real Madrid, Manchester United and Chelsea are said to be keeping tabs.

According to Milanese paper Il Giornale, agent Mino Raiola wants his client to wait for the proposed takeover by the Sino Europe Sports group to complete before any decision is made.

Chelsea's interest in the Italian stopper is understandable if the latest rumours surrounding their No1 Thibaut Courtois are to be believed.

The 24-year-old has been linked with a move to Real Madrid in the summer and The Sun reports the Belgian 'keeper is keen to move back to a city he lived in for three years while playing for Real's rivals Atletico.

The goalkeeping merrygoround in west London doesn't stop there, however, The Blues are said to have put a £12m price tag on back-up Asmir Begovic amid reported interest from Bournemouth.

Despite the 29-year-old Bosnian playing just four times for Chelsea this season, the south coast club are thought to see him as a long-term option to replace their 36-year-old stopper Artur Boruc.

Elsewhere, West Brom have reportedly agreed a deal with Hull City for midfielder Jake Livermore.

The 27-year-old is said to have attended a medical at the Hawthorns on Thursday ahead of a proposed £10m deal, according to Sky Sports.

Another man said to be on his way to the Baggies is Watford striker Odion Ighalo.

Free agents 2017: 20 footballers whose contract runs out in the summer Show all 20 1 /20 Free agents 2017: 20 footballers whose contract runs out in the summer Free agents 2017: 20 footballers whose contract runs out in the summer 1. Santi Cazorla - Arsenal The Spanish midfielder injured his Achilles in the Gunners’ 6-0 win over Ludogorets in October and had to have ankle surgery, which he is still recovering from. Cazorla also missed seven months of the previous season due to injury and it remains to be seen whether Arsenal will deem it worthwhile to tie him down for another year. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 2. Per Mertesacker - Arsenal Injured since the summer, Mertesacker hasn’t featured at all for Arsenal this term. The German defender is expected to return in a few weeks but he may find it difficult to break back into the starting XI, especially after Arsene Wenger bought Shkodran Mustafi in the summer. There are also rumours he may be let out on loan until the summer. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 3. John Terry - Chelsea Terry picked up an injury after initially being a part of Antonio Conte’s plans. He is available for selection now, however the Italian has opted to change his formation and Terry has been left frustrated. At the age of 36, his time at Chelsea may be over. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 4. Yaya Toure - Manchester City The 33-year-old’s agent has been trying to force a move away for some time, but Toure has recently seen more game time for City. This is his sixth season with the club, and they may be looking to get him off the wage book and bring in some fresh blood. AFP/Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 5. Zlatan Ibrahimovic - Manchester United It is unknown whether United will use the one year option on Ibrahimovic’s contract to extend his stay at the club but the Swede has performed admirably. Questions were raised over whether he was too old to perform in the Premier League but the 35-year-old has answered his critics, scoring 18 goals in 28 appearances – including 13 in the Premier League. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 6. Michael Carrick - Manchester United United are unbeaten in all competitions when the midfielder has featured this season. Despite not being favoured by Jose Mourinho in the early stages of his reign, Carrick now seems to be one of the first names on the Portuguese boss’ team sheet. But, at the age of 35, will United be looking to tie him up to another deal? Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 7. Saido Berahino - West Bromwich Albion The striker has been exiled from the first team since his strop back in 2015 when the Baggies rejected two bids from Tottenham. The 23-year-old took to Twitter to say he would never play for West Brom again. The club have approached him a third time about a new contract worth a reported £55,000-a-week but reports have suggested that he is refusing to sign. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 8. Adrian - West Ham United The 30-year-old goalkeeper is out of contract in the summer but the club do have an option to extend it by two years. However, Adrian has recently lost his place in the team to Darren Randolph, after starting the first 11 games and conceding 20 goals. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 9. Jesus Navas - Manchester City The pacey winger has received heavy criticism since moving to the Etihad for his lack of end product and has been used sparingly by Guardiola this season. It might be his last year with City. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 10. Taison - Shakhtar Donetsk The 28-year-old almost joined Chelsea from Metalist Kharkiv back in 2013 but opted instead to stay in Ukraine with Shakhtar. He hasn’t been used as much as he was at the beginning of the season which could signal a possible exit in the summer. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 11. Arjen Robben - Bayern Munich The Dutchman has been one of the best talents in the world over the last 10 years but his time may be drawing to an end at Bayern. His highlight in Germany was helping the club lift the Champions League after his late winner in the 2012/13 final against Borussia Dortmund. It is believed that Bayern will be hoping to tie him down to another contract. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 12. Fernando Torres - Liverpool The Spanish forward’s reputation has been severely damaged since his £50m move to Chelsea. He struggled with the Blues, and AC Milan, before moving on to Atletico where he has only scored twice this term, both coming in the 5-0 drubbing of Sporting Gijon. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 13. Pablo Zabaleta - Manchester City The Argentinian right-back has not been used as much under Guardiola, with the Spanish coach preferring to rotate between him and Bacary Sagna. Guardiola has said that he must prove himself under his style of football to in order to earn a new deal. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 14. Branislav Ivanovic - Chelsea Ivanovic was heavily involved in the first six games of the campaign, but like Terry, fell victim to a formation change by Conte. The change of tactic and acquisition of David Luiz means that the Serbian has fallen further down the pecking order and usually features from the bench. AFP/Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 15. Glen Johnson - Stoke City The Stoke right-back started the season with a thigh strain and then followed that up with a hamstring injury to miss eight of the first 11 games. Since then he has been ever-present for the Potters and with the option of a year extension on his contract, it’s likely they’ll look to get him to put pen to paper. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 16. Lucas Leiva - Liverpool It looked highly likely that the Brazilian would be going on loan to Inter in January but the Nerazzurri put the deal on hold while they looked to secure the signing of Roberto Gagliardini from Atalanta. The Brazilian has mainly made cameo appearances this season and after almost a decade at the club, he may be moved on. Getty Images Free agents 2017: 20 footballers whose contract runs out in the summer 17. Bacary Sagna - Manchester City The former Arsenal right-back has only featured in 10 Premier League games this season. As with Zabaleta, Guardiola has told him that he must perform well and adapt to his style of play if he wants to stay with the club further. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 18. Gael Clichy - Manchester City Guardiola has been rotating his left-backs as well as his right-backs but at times Clichy has found himself in central midfield under the Spanish boss’ new system. Like both Sagna and Zabaleta though, he is over 30, and City believe they have youngsters who are capable of replacing them. Like Zabaleta and Sagna, Clichy has a lot to prove in the second half of the season. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 19. Mario Balotelli - OGC Nice To say the Italian forward is a maverick would be somewhat of an understatement. This season, despite seeing his Nice side top Ligue 1 at the winter break, Balotelli has racked up either a booking or a goal in every game, as well as two red cards. His goalscoring record could prove vital for Nice, having netted eight times in nine outings for the league leaders. Getty Free agents 2017: 20 footballers whose contract runs out in the summer 20. Daniele De Rossi - AS Roma A stalwart for Roma and the Italian national side but will he follow in the footsteps of club great Francesco Totti? The 33-year-old is spending his 15th year in the senior team after making his way through the academy. The midfielder is a mainstay in the team and it’s expected that a new contract will be signed before this one runs its course. Getty Images

The two clubs have agreed a fee of £17m according to Sky Sports, despite the player scoring just twice this season.

If Oghalo does make the switch to the West Midlands he could replace wantaway striker Saido Berahino who is said to be on his way up the M6 to Stoke.

The Potters are said to have agreed a £12m deal for a player who has been sidelined at the Hawthorns since pushing for a transfer to Tottenham in August 2015.

According to the Stoke Sentinel, Mark Hughes has been told by the club's hierarchy that he can sign Berahino even if Bojan Krkic's move away - most likely to Middlesbrough - doesn't go through.

Another player frozen out of the first team at his club, Ashley Young, could also be on his way - but to the riches of the Far East instead of Staffordshire.

The Daily Mirror reports the Manchester United winger is weighing up an offer from Shandong Luneng - and who can blame him? The Chinese Super League side are said to have put a deal worth £16m-a-year on the table - after tax. The only downside? Young will have to suffer coach Felix Magath's notoriously brutal training sessions.

West Ham have agreed a fee of £8m for Southampton defender Jose Fonte after he handed in a transfer request, according to ESPN.

Vincent Janssen has rejected an approach from Galatasaray to fight for his place in the Tottenham first-team, according to Dutch broadaster Omroep Brabant.

And finally... Manchester City are said to have paid a record transfer fee to sign a 13-year-old.

Pep Guardiola's side, who yesterday completed the signing of Brazilian Gabriel Jesus, reportedly paid Southend £175,000 for the services of Finley Burns.
