Jose Mourinho has promised one of Chelsea’s brightest young prospect, Ruben Loftus-Cheek, that he will not be sold as Nemanja Matic once was and will be playing for the first team next season.

In light of the £2m paid to re-sign Matic, the Chelsea manager has changed the trading policy on academy players so that the club exert “control” over the future of a player, even if he is sold, with clauses in their favour if they ever seek to re-acquire individuals. But in the case of Loftus-Cheek, a 19-year-old from Lewisham who has been with the club since the age of eight, Mourinho said there is a clear future.

Loftus-Cheek was given his debut by Mourinho against Sporting Lisbon in December and also came on as a substitute in the 1-1 draw with Manchester City in the league in January. He is a midfielder who has risen quickly through the junior sides at the club and is now a regular for the Under-21s team.

PSG vs Chelsea - combined XI Show all 11 1 /11 PSG vs Chelsea - combined XI PSG vs Chelsea - combined XI GK: Thibaut Courtois This isn't even a selection between the PSG and Chelsea goalkeepers - it's a selection between the Chelsea No 1 and No 2. PSG would agree as they have courted both to replace Salvatore Sirigu in recent months. Jose Mourinho has handed the gloves back to the Belgian, who has recovered from a shaky spell last month - Courtois was the reason Chelsea won at Upton Park. PSG vs Chelsea - combined XI RB: Branislav Ivanovic The Serbian is the best at his position in the Premier League and one could make a convincing argument that he is the best right-back in world football, although he made some uncharacteristic errors at West Ham. Rarely beaten, he also carries a good attacking threat as a crosser and from set-pieces. Gregory van der Wiel is pretty much a winger playing in defence, he relies way too much on his pace to get him out of trouble - Eden Hazard will be looking forward to facing him again. Getty Images PSG vs Chelsea - combined XI CB: Thiago Silva The Brazil captain, named to the Uefa Team of the Year, is one of the premier defenders in world football; Brazil would not have lost to Germany 7-1 in the World Cup with him in the side. Gary Cahill has been back to his old spell after being dropped a month ago, but isn't a patch on Silva. Getty Images PSG vs Chelsea - combined XI CB: John Terry David Luiz may come with the £50million price-tag but Chelsea fans will know his (and John Terry's) true value as a centre-back. This is an easy decision, Luiz may look Hollywood when he blazes about the pitch, but he's not a good defender. Chelsea were laughing all the way to the bank in the summer. PSG vs Chelsea - combined XI LB: Cesar Azpilicueta The Spaniard has looked slightly ragged in recent weeks but he remains one of the best full-backs in world football. Maxwell, now 33, is serviceable but will be one of the players Chelsea will look to expose. PSG vs Chelsea - combined XI CM: Nemanja Matic Thiago Motta is back from injury but he is a level below the giant Serbian, who returns from suspension after his altercation with Ashley Barnes. Matic has been critical to Chelsea's title and European push this season and Jose Mourinho will expect another big game from him. PSG vs Chelsea - combined XI CM: Blaise Matuidi The energetic midfielder is absolutely key for Laurent Blanc's team, tasked with the job of stifling Cesc Fabregas. Matuidi, who drives the team forward, was hugely impressive in Paris and edges in front of Ramires, who could perform a similar job at Stamford Bridge. He will have his work cut out by the Spaniard, however. Getty Images PSG vs Chelsea - combined XI CM: Cesc Fabregas The Spanish maestro has not been as good as he was earlier in the season with a heavy work load seemingly catching up. But he is better than anything PSG are able to field in the middle. Marco Verratti is an exciting young player but has a long way to go to reach Fabregas' level. Getty Images PSG vs Chelsea - combined XI RW: Javier Pastore The Argentina winger was unable to start in the first leg as he was carrying a slight injury but he is fit and firing now. PSG have won three and drawn one of their last four since his return, with Pastore scoring once and adding two assists. Willian's energy and work rate is crucial to the way Chelsea play, but he has just eight goals and eight assists since joining the club. Getty Images PSG vs Chelsea - combined XI LW: Eden Hazard An easy choice and one that both managers would surely agree on. PSG are huge admirers of the Belgian winger and have constantly been linked with him in the last couple of seasons. Edinson Cavani is a hugely talented player but has to play out of position to accommodate Ibrahimovic. Getty Images PSG vs Chelsea - combined XI ST: Zlatan Ibrahimovic A tough decision picking the Swede over Diego Costa, who himself has enjoyed a stellar season. In real life neither club would swap their striker for the other, but Zlatan nudges slightly ahead on current form - Costa hasn't scored since 17 January.

Mourinho said: “At the age of 18, 19 sometimes you don’t believe that the player can go in a certain direction so you make a couple of million [selling him] and you are just happy with that. At academy level you know clearly that not everyone is going to be players for your first team.

“So sometimes if you can capitalise on that and make money in small deals you can make the money you need to invest again and again and again in the academy, to get the right talents that you bring to the first team. And [those] you bring to stay [in the first team].
