Manchester United 4-0 Norwich: Giggs hails Mata 'masterclass'

Manchester United's interim player-manager Ryan Giggs hails Juan Mata's performance as "a masterclass" after the substitute scored twice in United's 4-0 win over Norwich at Old Trafford.

Wayne Rooney's penalty had the hosts in front at the break and the striker added another just after half-time before record-signing Mata, left out of the starting 11 by Giggs, came on to score two from close range.

Giggs - taking charge of United for the first time - admitted that he did not sleep the night before the game, worried about leaving team-mates out of the match-day squad.
