Chelsea interim manager Guus Hiddink insists Cesc Fabregas will not be leaving Stamford Bridge during next month's transfer window.
Fabregas has suffered a dip in form this season and has been linked with a move to Juventus and Inter Milan amid reports Hiddink favours a more defensive shape to his midfield.
Hiddink, however, insists no player will be departing in January as Chelsea seek to improve on their Barclays Premier League position of 14th.
"We need all the players here until the end of the season," the Dutchman said.
"Chelsea are still in a position where we have to improve to get up the table, so we need all our players at the moment. So we don't talk about the rumours.
"Cesc is coming in with a smile, which is what I always like. Players come in with a smile and not a worn out face."
Discussions have been held between Chelsea and Major League Soccer club Montreal Impact over Didier Drogba returning to Stamford Bridge and Hiddink believes the Ivorian would be best suited to a hands-on coaching role.
"Didier is that rare kind of ex-player with big status who would be very good for any club to have, especially him because he's a Chelsea legend," Hiddink said.
"But he has a contract with Montreal at the moment, and we have to respect that also.
"In what capacity depends on the player himself. You have to give them time and opportunities to find out what's best for them.
"It might be on the coaching staff or as ambassador, but that's a bit more of an official function for me.
"Guys like him need to be in the squad helping younger players, all the players, with their huge experience.
"I'm not in favour of a big ambassador travelling the world in a tie. I think they must give their huge experience to all, especially young kids, but also the older ones when they are in trouble in their career."
