Stoke City have signed Sheffield United attacking midfielder Mark Duffy.

The 33-year-old is the Potters' tenth signing of the summer.

Speaking after the club's website, Duffy said: "I am really pleased to be here - it has been a crazy few hours but I am delighted.

"As soon as I heard of Stoke's interest, and given my circumstances at Sheffield United where maybe my game time would be a little bit limited, this was the only place I wanted to come."
