Kalvin Phillips scored his first goal for Manchester City when they beat Red Star Belgrade in the Champions League on 13 December, but it is unlikely to be enough to prolong his stay at Etihad Stadium.
Newcastle have been strongly linked with a move for the England midfielder, while a transfer overseas could be an option with Italian giants Juventus also reported as a possible destination.
Jadon Sancho (Manchester United)
Linked with: Borussia Dortmund
It has long been clear Jadon Sancho’s future lies away from Old Trafford, with the forward having been exiled from the first team after a fall out with Manchester United boss Erik ten Hag.
His former club Borussia Dortmund have been mooted as a possible destination but wages appear to be the main stumbling block.
The 26-year-old will join for the rest of the season, with an option to turn the transfer into a permanent deal.
Aaron Ramsdale (Arsenal)
Linked with: Chelsea, Newcastle
England international Aaron Ramsdale lost his Arsenal place to David Raya in September, and with a European Championship next summer, may seek a January move to ensure regular first-team football.
Chelsea and Newcastle have both been linked with a move for Ramsdale.
Conor Gallagher (Chelsea)
Linked with: Tottenham
Conor Gallagher has been a first-time regular at Chelsea this season and even captained the side on a number of occasions, which makes it somewhat surprising that he could be heading elsewhere in January.
The Blues are said to be needing to balance the books after some big spending over the past 18 months and Gallagher could be sacrificed to help fund that.
Arsenal faltered in their title challenge on 28 December when they lost 2-0 at home to West Ham – a game that highlighted a need for someone to put away the many chances they created. Mikel Arteta’s side had 30 efforts on goal with only eight on target.
Brentford striker Ivan Toney has long been rumoured to be a priority January signing to bolster Arsenal’s attack.
Toney is still serving his eight-month ban from football for breaching the Football Association’s betting rules but is set to return on 17 January.
Joao Palhinha (Fulham)
Linked with: Arsenal, Bayern Munich, Liverpool
Fulham attempted to warn off clubs interested in midfielder Joao Palhinha by giving him a new contract in September, but their resolve looks set to be tested in January.
Arsenal, Bayern Munich and Liverpool have all been linked with a move for the Portugal international.
Injuries have limited Thomas Partey’s appearances at Arsenal this season and with Mikel Arteta believed to be needing to sell players to fund arrivals in January, the midfielder could make way.
The 30-year-old is back in training after a muscle problem kept him out for two months and he has been linked with a move to Italian giants Juventus.
Trevoh Chalobah (Chelsea)
Linked with: Crystal Palace, Bayern Munich, Roma
Like Conor Gallagher, Trevoh Chalobah may have to leave Chelsea in January to help them balance the books.
The defender has not played for the Blues all season after suffering a thigh injury during pre-season.
The England midfielder has recently returned for Arsenal from injury but could move in January if Mikel Arteta needs to move things around to bolster his squad.
