Roy Keane showed that he is capable of brief moments of levity by pulling off a devastatingly simple prank on a member of the Republic of Ireland coaching staff during a training session.

Just as veteran coach Seamus McDonagh was lining up to take a shot on goal, Keane moved his ball at the crucial moment.

McDonagh promptly ended up on his backside while everybody else ended up in stitches.

A true training ground classic.
