Arsenal

After he completed the summer purchases of Shkodran Mustafi and Lucas Pérez, Arsène Wenger described his squad as the “most mature” he had assembled for a long time, and it is difficult to see him adding to it in a major way during January. Don’t forget, Per Mertesacker and Danny Welbeck will be like new signings when they return from their injuries.

Possible signings Targets like the Valencia left-back José Gayà and Borussia Dortmund’s Marco Reus are more for next summer.

Possible outgoings Yaya Sanogo, anyone? Carl Jenkinson.

Estimated budget for January window Whatever Wenger wants, he can have.

David Hytner

Bournemouth

Eddie Howe’s biggest concerns are defensively, with his team having conceded 15 goals in their past six matches. To get some perspective, Bournemouth have conceded more goals than Middlesbrough and as many as Sunderland (31). In attack, neither Benik Afobe nor Lewis Grabban, both recruits last January, have provided stern enough competition for Callum Wilson or Joshua King. Howe has said he does not expect January to be a “huge window” for the club but there is certainly room for improvement.

Possible signings Ben Mee (Burnley), Kieran Trippier (Tottenham), Tom Cairney (Fulham).

Possible outgoings Callum Wilson, Lewis Grabban, Max Gradel, Ryan Allsop.

Estimated budget £12m.

Ben Fisher

Burnley

Commanding at home, where Liverpool, Everton and Watford are among those beaten, but weak away, where they have taken one point from a possible 24 and scored just twice, Burnley need greater resilience and firepower to enhance their prospects of staying in the Premier League. An early move for Joey Barton has been thrown into question over his FA betting charge.

Possible signings Joey Barton (free, confirmed), Jordan Rhodes (Middlesbrough).

Possible outgoings Lukas Jutkiewicz (will make loan move to Birmingham City permanent), Michael Keane and Patrick Bamford.

Estimated budget £10m.

Andy Hunter

Chelsea

Chelsea could not refuse the money on offer from Shanghai SIPG for Oscar, and Antonio Conte has had discussions with the board stressing the need to replace the Brazilian. The club always hoped to be active in the next two windows, though the calibre of signing they are seeking to make may have to wait until the summer.

Possible signings Virgil van Dijk (Southampton), Radja Nainggolan (Roma), Djibril Sidibe, Tiemoué Bakayoko (both Monaco), Antonio Rüdiger (Roma), Simon Kjaer (Fenerbahce), Michael Keane (Burnley), Franck Kessié (Atalanta).

Possible outgoings Oscar (Shanghai SIPG, £60m, confirmed), Ruben Loftus‑Cheek (Newcastle/West Ham, loan), Asmir Begovic (West Ham).

Estimated budget £60m.

Crystal Palace

The priority is a left-back to replace the injured Pape Souaré and offer some balance to the team, but Palace also need a back-up forward now that Connor Wickham is out for the season and Loïc Rémy is proving so injury-prone.

Possible signings Georgi Shchennikov (CSKA Moscow), Ben Davies (Tottenham Hotspur), Neil Taylor (Swansea City), Kieran Tierney (Celtic), Kieran Gibbs (Arsenal) Charlie Taylor (Leeds), Aleksandar Mitrovic (Newcastle), Leonardo Ulloa (Leicester City).

Possible outgoings Jordon Mutch (Aston Villa).

Estimated budget £15m.

DF

Everton

There seems little doubt that Everton’s squad requires a bigger overhaul than Ronald Koeman anticipated when arriving from Southampton in the summer. Goalkeeper, central defence, central midfield, cover at left-back and better options up front – several of them - must all be on the wishlist.

Possible signings Morgan Schneiderlin, Memphis Depay (both Manchester United), Ademola Lookman (Charlton Athletic), Manolo Gabbiadini (Napoli), Michael Keane (Burnley).

Possible outgoings James McCarthy, Oumar Niasse, Arouna Koné, Darron Gibson, Gerard Deulofeu.

Estimated budget £40m.

AH

Hull City

With the Allam family keen to sell up but viable buyers thin on the ground, Mike Phelan is unlikely to have much money to spend. With Robert Snodgrass having only 18 months remaining on his contract, the manager’s biggest battle looks certain to be a tug of war with the gifted Scotland winger’s assorted suitors. Phelan, though, desperately needs to strengthen in attack.

Possible signings Jordan Rhodes (Middlesbrough).

Possible outgoings Robert Snodgrass, Harry Maguire, Tom Huddlestone.

Estimated budget £10m-£15m.

Louise Taylor

Leicester City

A disappointing first half of the season has reinforced the need for the Premier League champions to strengthen. Subject to agreeing a work permit, Wilfred Ndidi, a defensive midfielder, will join from Genk for £15m. A central defender is considered a priority, with Burnley’s Michael Keane a long-standing target but now out of reach.

Possible signings Wilfred Ndidi (Genk).

Possible outgoings Jeffrey Schlupp, Leonardo Ulloa, Bartosz Kapustka, Matty James.

Estimated budget £30m.

Stuart James

Liverpool

Jürgen Klopp might have resisted any major changes – as he did last year – but the loss of Danny Ings to a season‑ending knee injury and Sadio Mané’s commitments at the Africa Cup of Nations necessitate cover in attack. “It’s not about how many strikers,” Klopp has said. “We do not have many wingers.” He has also allowed Lucas Leiva to join Internazionale on loan.

Possible signings Christian Pulisic (Borussia Dortmund), Sardar Azmoun (FC Rostov) and Quincy Promes (Spartak Moscow).

Possible outgoings Mamadou Sakho (on loan).

Estimated budget £40m.

AH

Manchester City

Pep Guardiola has been careful to leave the possibility of signing a central defender open in January but said it will be difficult. But the head coach surely requires one as Vincent Kompany is injured again, John Stones was dropped recently and Nicolás Otamendi is an uneven performer. Guardiola does admit he needs a full-back. He would also jump at any chance to sign a workaholic prolific striker in the Alexis Sánchez/Luis Suárez mould but this appears a particularly difficult ask.

Possible signings Ryan Bertrand, Virgil van Djik, José Fonte (Southampton).

Possible outgoings None.

Estimated budget £100m-£150m.

Manchester United

Four consecutive Premier League wins may have altered José Mourinho’s view of the squad yet he is still considering adding a central defender, a right-back and an experienced goalscorer in the 24- to 29-year-old range. Whether one or any of these arrive in January rather than summer is in the balance.

Possible signings José Fonte (Southampton), Nélson Semedo (Benfica).

Possible outgoings Memphis Depay, Morgan Schneiderlin, Bastian Schweinsteiger.

Estimated budget for January window £100m.

JJ

Middlesbrough

Aitor Karanka urgently needs to add goals, creativity and probably crosses to his otherwise promising team and could also do with an extra central defender. It will be no surprise if he part-funds any purchases by selling the apparently unwanted Jordan Rhodes.

Possible signings Rudy Gestede (Aston Villa), Neven Subotic (Borussia Dortumund), Robert Snodgrass (Hull), Harry Maguire (Hull).

Possible outgoings Jordan Rhodes.

Estimated budget £10m-£15m.

LT

Southampton

Claude Puel looked as though he was a striker short when the summer transfer window ended and, with Charlie Austin now a long-term injury casualty, he certainly is. Cover up front, if only on loan, would appear wise. The priority is to retain the central defenders, Virgil van Dijk and José Fonte – both of whom have their admirers at bigger clubs.

Possible signings Sébastien Haller (Utrecht), Franck Kessié (Atalanta), Fabian Schär (Hoffenheim).

Possible outgoings Virgil van Dijk, José Fonte.

Estimated budget Depends on whether Van Dijk or Fonte are sold.

DH

Stoke City

With Jack Butland’s injury problems, resolving the goalkeeping situation at Stoke is a priority. Lee Grant has been excellent during his loan spell from Derby but that expires on 3 January and the two clubs remain apart on the 33-year-old’s valuation. The long‑running search for a striker also goes on, with Saido Berahino likely to come back into view.

Possible signings Lee Grant (Derby County), Saido Berahino (West Bromwich Albion).

Possible outgoings Peter Crouch.

Estimated budget £15m.

SJ

Sunderland

Reinforcing central midfield and central defence are the priorities but an injury-hit squad is understaffed throughout. Unfortunately for David Moyes the £140m club debt and £73m wage bill which leaves them in peril of exceeding Premier League wage cap rules dictates he must sell before he can buy and he is loth to lose Lamine Koné.

Possible signings Robert Snodgrass (Hull), Robbie Brady (Norwich), Phil Jagielka (Everton).

Possible outgoings Lamine Koné, Wahbi Khazri.

Estimated budget Zero – unless players are sold.

LT

Swansea City

Every department of the team needs strengthening, in particular defence, where Swansea have been awful. They need a new back four, plus a winger and a pacy centre-forward. They are also in the market for a defensive midfielder. You get the picture.

Possible signings Aleix Vidal (Barcelona), Tom Carroll (Tottenham), Leonardo Ulloa (Leicester).

Possible outgoings Kyle Naughton, Ki Sung-yueng.

Estimated budget £15m

SJ

Tottenham Hotspur

Mauricio Pochettino believes his squad has the right balance, with youngsters ready to push up to fill any gaps that might emerge. The manager has acknowledged the difficulties of the January market but he would move if any upgrades become available. He is a massive fan, for example, of the Crystal Palace winger, Wilfried Zaha.

Possible signings Wilfried Zaha (Crystal Palace), Ryan Sessegnon (Fulham).

Possible outgoings Tom Carroll.

Estimated budget £15m.

Watford

Watford were happy with their squad at the start of the season, but a spate of injuries, most seriously to their record signing Roberto Pereyra, has left them with positions to fill. Priorities are a creative No10 – Adalberto Peñaranda, on loan at Udinese, could be recalled – and a box-to-box midfielder to provide competition for Étienne Capoue.

Possible signings Ruben Loftus‑Cheek (Chelsea), John Obi Mikel (Chelsea).

Possible outgoings Ben Watson, Abdoulaye Doucouré.

Estimated budget The club are targeting loan deals, but could spend up to £15m should the right players become available.

Simon Burnton

West Bromwich Albion

Tony Pulis will see investment in this transfer window as the key to ensuring that a promising start to the season does not tail off. Albion’s pursuit of Morgan Schneiderlin is a sign of the club’s intent, with a winger and a striker among the other targets.

Possible signings Morgan Schneiderlin (Manchester United), Jeffrey Schlupp (Leicester).

Possible outgoings Saido Berahino.

Estimated budget £25m.

SJ

West Ham United

Their summer recruitment failed badly and there are two glaring gaps that need filling. The first is at centre‑forward where, despite recruiting Simone Zaza, Jonathan Calleri and Ashley Fletcher, none has taken flight at the London Stadium. The second position is right-back where a combination of injuries and bad form has led to both Michail Antonio and Edimilson Fernandes filling in.

Possible signings Laurent Depoitre, Carlos Bacca, Daniel Sturridge, Carl Jenkinson (loan).

Possible outgoings Simone Zaza, Jonathan Calleri.

Estimated budget £15m.
