Speaking to Chelsea's official app, The 5th Stand, Terry said: "Still undecided what I'm doing next".
Former Chelsea captain John Terry is reportedly considering a sensational return to Stamford Bridge after rejecting a lucrative contract from FC Spartak Moscow. I wanted to stay fit in case something came along.
The Blues have won all four of their opening games in the league so far this season under the newly appointed Sarri and are only behind Liverpool on goal difference in the standings.
Makelele won two Premier League titles with the Blues. I think so (that this season is too soon for Chelsea), but I hope not.
"If he wants to help us, I'm very, very happy".
The 59-year-old Sarri says "unfortunately at the moment I am not able to stop". "[But] in this first period, for me, it was very important not to change, especially the defensive line".More news: Samsung Galaxy S10 Variant to Feature 5 Cameras
"I said before I want to give space to the young players", Sarri added.
"At the moment, I can only see City or Liverpool [winning it], at the moment", he told a media conference.
"We need another step to be at the same level".
The Italian added: "I think tomorrow will be a very hard game because, mentally, the match after the break is always very hard".
Emerson Palmieri, Davide Zappacosta (both illness) and Ruben Loftus-Cheek (shin) are doubts and could miss out. "We will play against a very physical team, so I think it we want to get points, we need a very good performance".
"It's a hard game for everybody, against Cardiff", Sarri added.
