Stoke City have signed Kevin Wimmer from Tottenham for £18million.
Wimmer, 24, sealed his move and signed a five-year contract with Mark Hughes' side on Tuesday, having completed his medical on Monday.
He becomes Stoke's seventh signing of the transfer window and the fourth defender to come in after the arrivals of Bruno Martins Indi, Kurt Zouma and Josh Tymon.
Stoke boss Hughes told his club's official website: "Kevin is an undoubted talent and he will significantly add to the quality of the group of players that I already have at my disposal.
"We put a real emphasis on trying to enhance the defensive areas of the squad this summer and we feel that we have been able to do that.
"We brought Kurt Zouma in earlier in the window and managed to bring Bruno Martins Indi back to the club following his loan spell last season, so bringing Kevin here too, a player I admire greatly, gives me real strength in depth in those central positions."
