Chelsea manager Jose Mourinho has no plans to improve his squad during the January transfer window but has not ruled out reacting to departures from Stamford Bridge.
Juan Mata and Kevin de Bruyne both left the Blues last January, forcing the club into signing Mohamed Salah and Nemanja Matic.
And Mourinho has refused to rule out a repeat of last January's dealings but admits Chelsea are not looking to actively improve their squad.
"Last year you ask and I didn't lie to you but at the end of the day Mata was sold," he said. "At this moment I keep saying the same I am happy with the squad, we have a good group to play football but also a good group to live together. I don't want to lie to you.
"I have two of the best goalkeepers in the Premier League and I have a fantastic defenders who defender very well.
"We concede five in one game, that is better than conceding five in losing five matches. We made mistakes in that game but after result we beat Newcastle and another clean sheets and back to normality."
Having reclaimed their advantage at the top of the Premier League following the win over Newcastle United, Mourinho's side have the chance to open up a five-point lead when they travel to Swansea City.
Chelsea have received a huge boost ahead of the game with the news that goalkeeper Thibaut Courtois is ready to return from a finger problem, while full-back Cesar Azpilicueta will return from a groin problem next week.
"Yeah I am not saying he is 100% but not many are 100% to play football during a season," the Chelsea boss said of Courtois. "There is always a pain here or a pain there. He had a problem in is finger against Tottenham but he is ready to play.
"In this moment, his fitness is not 100%. Azpilicueta was less than we thought, he was intelligent that a big injury was coming and he stopped and next week he will be training."
