Terry has returned to his best form under Mourinho this term and has been a virtual ever present as Chelsea push for honours both domestically and in Europe.
Despite his return to form, there is some doubt as to the future of Terry at Stamford Bridge.
Mourinho, though, wants Terry to continue his career at Chelsea and is positive a deal can be thrashed out.
"The manager wants him to stay; the club know I want him to stay, the club want him to stay, he wants to stay, so normally he is staying," Mourinho is quoted as saying by ESPN.
A potential stumbling block is the length of contract on offer. Like many clubs, Chelsea’s preferred position is to offer players in their 30s one-year extensions.
What Should Chelsea Offer John Terry?
Terry is believed, according to Neil Ashton of the Mail Online, to want a longer deal. Mourinho may be keen to keep his captain at the club, but he has suggested he will not lean on those making the deal.
"The only idea I have is that the manager wants him to stay but the contracts are between the player and the club, I never have any involvement in this. They will find the right moment," Mourinho said.
While talks are likely to take a backseat ahead of the final weeks of the season, Terry could certainly strengthen his position with a string of commanding performances.
Chelsea face Paris Saint-Germain on Tuesday needing to overturn a 3-1 first-leg deficit. Should Terry lead the side to the semi-finals of the Champions League, he will not do his own personal situation any harm.
