But Sarri does not see his side battling for the title at the end of the season, instead thinking Liverpool and City will be the two teams vying for silverware.
Speaking to Chelsea's official app, The 5th Stand, Terry said: "Still undecided what I'm doing next".
Meanwhile, NAIJ.com had earlier reported that Chelsea manager Maurizio Sarri has waxed lyrical over David Luiz - insisting the Brazilian has a "big future" at Stamford Bridge.
Asked about the prospect of Terry returning, Sarri added: "He told me he wants to play".
But in the last 12 meetings, Chelsea won 10, including both previous Premier League encounters in the 2013-14 season. "For the moment, I'm really very happy to stay here".
"If there is a pitch and there are 11 players, I feel at home anywhere", Sarri said. He has won everything with the club so it is up to him. 'Fortunately, we have very strong young players; (Ruben) Loftus-Cheek, (Callum) Hudson-Odoi, Ampadu, and I'd like to give them the right space.

But I think the most important thing is everyone can make a mistake. 'He already knew in the moment that it was a big mistake . Only we need to try (to ensure) that he understands that it was a mistake. "It's a massive lesson for everyone".
Chelsea return to domestic action against Cardiff City on Saturday, and Sarri expects a tough game for his returning players. "[But] in this first period, for me, it was very important not to change, especially the defensive line".
"We need another step to be at the same level".
Worldwide football should be played at the end of every campaign rather than on specific dates throughout the club season, according to Chelsea boss Maurizio Sarri. So I know that the matches after the break are very, very hard.
Chelsea will also welcome back Cesc Fabregas who has been sidelined since the season started with an injury and Sarri is ecstatic that the former Arsenal midfielder will be fit enough to feature. It is hard game for everyone against Cardiff.
"We play against a very physical team, so I think if we want to gain points we need a very good performance tomorrow".
