Sheffield United boss Chris Wilder isn't surprised by Mason Mount's impact at Chelsea.

Wilder saw plenty of Mount in the Championship last season during the midfielder's loan at Derby.

He said, “No surprise at all. If you look through Derby's season last year, he did fantastically well. They turned us over at their place, deservedly so. He was the heartbeat of everything they did and his absence from the team with injury coincided with their worst part of the season. His introduction back into the team led to their best part of the season.

“An outstanding player. Two of their outstanding young players had fantastic experiences in the Championship last season. He was the outstanding player in the Championship for me."
