The England goalkeeper is being linked with Arsenal and Tottenham.
But he is adamant he is happy with life at City.
Foster said: "I was at Watford on loan for two years and this is up there with that. I've loved every minute of this season. The dressing room we've got here and the spirit is fantastic.
"I wouldn't want to leave that to be honest with you. I'm back home in the area where I was born.
"I saw (West Brom striker) Peter Odemwingie being interviewed yesterday and he said a happy man at home is a happy man on the pitch.
"I totally agree with it."
Foster added: "It is nice to be linked (with other clubs) but it is always the way.
"You see Heurelho Gomes at Spurs make a mistake on Saturday and Tottenham are going to be linked with 10 keepers today.
"That's the way it is, but I'm happy here."
