Jose Mourinho: John Terry staying with Chelsea next season

"What I can guarantee is that John Terry will be a Chelsea player next season. I can guarantee that," said Mourinho at a press conference ahead of his side's trip to face West Ham United on Wednesday.

"I know what my board tells me and the player tells me and no doubt he is going to get his contract.

Terry joined Chelsea in 1998 and has made more than 600 appearances at the heart of their defence, signed a one-year contract extension at the end of last season.

"All of these big guys are difficult to replace, but you have to think what next and I think that is the best way to do things," Mourinho said.

Terry had said he was determined to enjoy a successful conclusion to his Chelsea career by continuing to confound his critics.

The 34-year-old hopes to earn an extension to his contract which expires at the end of the current campaign.

Terry scored the opening goal in a man-of-the-match display in Chelsea's Capital One Cup final victory over Tottenham on Sunday.

It was the first trophy of Jose Mourinho's second spell as Blues boss, with Terry still a central figure 10 years after the Portuguese's first Stamford Bridge silverware in the same competition.

"I am fighting for myself and my family, and to prove people wrong," Terry said.

"It doesn't come much bigger than that. I want to give it everything.

"I don't know how long I have left. Hopefully I have a few years left but if this is my last year then I hope it will go out on a bang.

"I have my little target to play next year but beyond that, two or three years (more), I don't know."

Chelsea policy dictates that players over the age of 30 are granted 12-month deals.

Terry signed his current deal 48 hours after the end of last season - Mourinho's first back at Stamford Bridge - and could be made to wait until the end of the current campaign before a new deal is negotiated.

"The uncertainty has helped me positively, not having four or five years (under contract) as you get older.

"The roles have reversed and now the power is in the club's hands. That has inspired me."
