Chelsea boss Jose Mourinho has confirmed that Blues captain John Terry will remain at Stamford Bridge next season.

The 34-year-old defender, who is currently on the last year of his Chelsea contract, recently stated that he would be "fighting" for a new deal at Stamford Bridge, insisting that he still has a "few years" left in him.

However, he also that he would be calling quits on playing career if he failed to secure a new deal at the West London club, vowing to never play for another club.

And now Mourinho, who has managed to bring Terry back to his best, says that he can "guarantee" that the former England defender will stay at Stamford Bridge beyond this season.

"What I can guarantee is that John Terry will be a Chelsea player next season. I can guarantee that," said Mourinho, according to ESPN. "[Terry] is going to get his contract. It will be before the end of the season, for sure."

Meanwhile, there is also a lot of uncertainty surrounding Petr Cech's future as it is believed that the goalkeeper is looking to leave Stamford Bridge after being displaced by Thibaut Courtois as the number one goalkeeper at Stamford Bridge.

And Mourinho says that he will not stop the 32-year-old if he wishes to exit Stamford Bridge at the end of the season, despite insisting that he will not be allowed to leave for cheap.

"I don't think Petr is a guy to be persuaded," said Mourinho, according to the Telegraph. "I will just wait, wishing his decision is to stay. But I don't waste my time trying to persuade him. If he tells me he wants to leave I will tell him my opinion: that he is one of the three best goalkeepers in the world, so huge money."

Chelsea, who are right on course of their first Premier League title since the 2009/10 season, face London rivals West Ham at Upton Park on Wednesday.

The Blues are five points clear, with a game in hand, at the top of the Premier League table after their closest rivals Manchester City were beaten at Liverpool on Sunday.

And the Portuguese, who admits that City's recent defeat against the Reds was beneficial to Chelsea, says that his side need "31 points" from their remaining 12 Premier League fixtures to win the title.

"When our direct opponents lose points, it's good for us. We have five points advantage, which in this competition is not a lot," he added. "Mathematics plays a role in all of this - 12 matches to go, 36 points to play, 36 minus five, we need 31 points.''
