Manchester United defender Nemanja Vidic was pleased with the performance of teenager Michael Keane during his side's pre-season game against Valerenga on Sunday.

Keane made his first senior start for the Red Devils in Oslo, playing a full 90 minutes in which neither side managed to break the deadlock.

The 19-year-old defender's performance at left-back caught the eye of Vidic, who played in central defence.

"I'm glad he's had a full ninety minutes," Vidic told MUTV. "He was confident on the ball and it's a big change from the youth academy, obviously, and I think he did really well."

United's next pre-season friendly is against Barcelona on Tuesday.
