The Swiss defender had been part of City’s ‘Elite Development Squad’ and got a taste of first team action on their US tour last summer but will switch over to the red side of Manchester with the hopes of breaking into the first team.
Speaking to the club’s official website, the 19 year old said:
“I am very happy and it is an honour to sign for Manchester United.
“I can’t wait to get started, to work hard and do everything I can to help the team. I am looking forward to showing everybody what I can do on the pitch.
“I am very thankful to Sir Alex Ferguson for bringing me to such a great club.
“Manchester United has a long history of younger players coming through and hopefully I can follow and do the same.”
