The English centre-back's current contract with the Blues runs out at the end of next season.
"On the pitch, I had a terrible injury - that sort of set me back a little bit," he told Sky Sports News. "I was keen to come back from the Euros and continue with my football, and unfortunately with the injury that hasn't been the case and I've been in and out of the side.
"It's not an ideal situation for me but, at the same time, I understand that if other players are playing well around me, I keep my head. People have to realise that I've got a year left at Chelsea after this. People have spoken about no new contract and this kind of thing, but it's not even on the agenda at the moment.
"They may sit down with me once the season has finished and we'll start talking then. Whether it's a yes or a no I'll continue to give my very best until my contract finishes at Chelsea."
Terry has been at Chelsea his entire career.
