The 20-year-old has not yet made a first-team appearances for City, since joining the club from Norwegian side Skeid in 2008.

"I wasn't sure what was going to happen towards the end of last season or what City were thinking so it was great to be offered a new deal," he told the club's official website.

"I didn't know if I'd be on the pre-season tour or not so I was really happy to be included in the party because it is really good to be around the senior players that are here in Austria and things couldn't be going better.

"I'm enjoying training, feeling sharper every day and it was great to get a run out against Al Hilal on Friday evening.

"We have two more games left on this tour and I hope I can be involved in those matches, too."
