Who do you buy for the club that has everything? Such is the sheer strength of Chelsea's squad, it is little wonder transfer chatter from a Blues' perspective has been at an all-time low heading into the January window.

The success of the club's summer business ensures their assault on domestic and European football does not need to be supplemented mid-season. While clubs have cast envious glances at some of the more peripheral members of the Blues squad in recent weeks, you'd imagine manager Jose Mourinho would be more than happy to completely ignore proceedings happening off the pitch in January.

What they need

What do Chelsea urgently need? Absolutely nothing. Their strength in numbers coupled with the near-flawless fitness records of so many of their stars – Diego Costa's hamstring problems have been Mourinho's only real headache this season – means there is certainly no need to panic buy in the new year.

Who could join?

Despite the current strength of their first-team squad, Chelsea's internal recruitment process carries on regardless. The club are currently in talks with Croatian striker Andrej Kramarić over a January move for the prolific 23 year old, one likely to have the view of making him the 28th player to leave the club on loan this season should he make the move to west London next month.

Who could leave?

Mohamed Salah, signed from under the noses of Liverpool this time last year, has been targeted by Inter Milan, while Spartak Moscow manager Murat Yakin recently vowed to do "whatever it takes" to sign the Egyptian. Unthinkable 12 months ago, Petr Cech has been restricted to just five appearances this season but the goalkeeper, his agent and Mourinho would all appear to be in agreement that an exit this winter is off the cards.

What the manager has said

"No [Chelsea are not looking to bring in new players in January]. We have a short squad but we've got good players, some younger, some older, but the squad is very, very good.

"Our project is to start and finish the season with the same group of players, so there will be nobody to leave and nobody to come in either."
