Lampard featured for City in yesterday's 1-1 draw.
Going into the game, Lampard told Soccer AM: "Jose Mourinho and the club from the top have said they'll love for me to be involved, whenever I want to go back."
He added: "Chelsea is like going back home and it feels such a big part of me. When you are part of Chelsea, I've seen it with people like 'Chopper' Harris and Peter Bonetti, they're still there to this day. It's a club that really looks after its players.
"If the opportunity was there to go back, I would love to, as I had such a long career there. It's a part of me - and that never changes."
