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 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."
Meanwhile, Blues midfielder John Obi Mikel believes the mood in the dressing room has definitely improved since Hiddink's arrival.
Chelsea turned to Hiddink again earlier this month to guide them out of a woeful campaign under Jose Mourinho this season, a spell that saw them fall to 16th place and within a point off relegation.
"We have moved on and the atmosphere has improved since the change of manager," Mikel said.
"Jose is a fantastic manager, but sometimes football is a cruel game and you have to move on. He came back to the club a second time and won two trophies but now he is gone. Is it the right decision? We will only see in the future."
The Nigerian is one of few players, along with defenders John Terry and Branislav Ivanovic, who were at the club during Hiddink's previous period in charge, when the Dutch manager led them to an FA Cup win. "He (Hiddink) hasn't changed much yet, but he was here before and he knows the place and all the staff," Mikel said.
"We are down there in the table for a reason so he can not come in and perform miracles.
"We have had three games now without losing, so (we) are making the right steps."
Mikel, who got limited game-time under Mourinho making just two starts in five league appearances, could not explain Chelsea's meek title defence this season. "It is difficult when you are not playing, as you do not really know what the problems are," Mikel added.
