Manchester City midfielder Ilkay Gundogan admits he could play out his career with the Premier League leaders.
The Germany international's contract runs to 2023.
He told Sky Deutschland: "I must honestly say that I can imagine it happening. The way they work here, not only athletically, but also in all areas around it, is something I have never seen before in my career.
"I feel that the club is more than just football in itself and it is just a nice feeling to be part of this family.
"I think that during my career I have had phases where I previously played just as well. The way I played football. What has been added this season are of course the goals. The numbers are much better, that is why it stands out even more right now."
