Johansson, who made his senior international debut for Sweden in October, said: “It’s brilliant to be here. Stoke City is a massive club and this is a proud moment for me and my family.

“One thing my teammates, coaches and the fans can be sure of is that I will work really hard.

“My Dad works hard, my Mum works hard, I come from a hard-working family and that’s the sort of person I always want to be, to make the most of living my dream and get as high as I can in the game.

“I have heard a lot about the Stoke fans, both home and away, and I’m told that their support is incredible, so I can’t wait for that.

“I share the ambitions of the Club and it’s a journey I really want to be part of, so I’m looking forward to getting started.”

Potters’ Goalkeeping Coach Darren Behcet added: “Viktor is a player I have always admired. He has tremendous shot-stopping ability and I like the confidence he has in coming off his line and commanding his penalty area.

“I’m looking forward to working closely with Viktor and I’m sure the fans will make him feel like one of our own.”
