He had this week been linked with a transfer to UEFA Cup finalists Rangers and Championship side QPR, however, Southgate sees the wide-man as a part of his plans for next season.
He said: "Despite what has appeared in some papers we have not had a single approach from any club about Adam Johnson, we have had absolutely no contact about Adam from either Rangers or QPR, nor do we expect to have any.
"As I have made it clear, he remains a big part in my plans for the club. Adam is a fantastic talent and I do not want to see him leave. He could be very, very special and I would not want to see him play for another club."
