The absence of Patrice Evra, who returned to Manchester to be with his pregnant wife during her labour, gave Keane an unexpected outing, but he savoured every moment of the Reds' goalless draw in Norway.
"It was strange," the youngster told MUTV. "I've not played there [left-back] for over a year now, but I thought I adapted quite well to the position and Rio and all the other players helped me out a lot, so I thought I did quite well.
"They've all got great experience and they're great players to play with. I grew up watching all of them and to play in the same team as them is great. I really enjoyed it."
