Ole Gunnar Solskjaer said: “Harry is one of the best centre-backs in the game today and I am delighted we have secured his signature. He is a great reader of the game and has a strong presence on the pitch, with the ability to remain calm under pressure - coupled with his composure on the ball and a huge presence in both boxes - I can see he will fit well into this group both on and off the pitch.

“He has a great personality and is a fantastic addition to the club.
