-Chelsea could recall one of their two left wing-backs currently out on loan. However, Ian Maatsen is unlikely to return from Coventry City at this stage with no PL experience.
-Emerson is the other possibility, but his loan at French Ligue 1 side Lyon includes a clause to make the move permanent in the summer, so breaking that wouldn’t be ideal for either club and perhaps the player himself.
-Everton will demand £25m for Digne permanently as they look to recoup fees on any outgoing players this January. A loan can’t be ruled out, but would probably involve a hefty fee plus an expectation to pay most, if not all, of Digne’s wages.
-AC Milan’s Theo Hernandez has been mentioned as a possible target. Chelsea and AC Milan have a good relationship. But with AC Milan being just four points off the top spot in Serie A, a move for Hernandez seems unlikely in the middle of the season.
-Barcelona will demand a sizeable fee for Sergino Dest to balance the books after just signing Ferran Torres.
-Chelsea might look at other options in La Liga. Alex Moreno from Real Betis is having a good season. But with Betis fighting for a CL spot in La Liga and qualifying for the knockout phase of the Europa League, he wouldn’t be cheap. Espanyol’s Adria Pedrosa is also being mentioned. He has 18 months left on his contract and could leave for a reasonable fee.
-Nicolas Tagliafico has started just three games for Ajax this season and the 29-year-old would surely be tempted to join Tuchel’s side. Chelsea have also previously been interested in him before they signed Chilwell from Leicester.
