Manchester United thrash feeble Arsenal

LONDON (Reuters) - The eagerly-awaited FA Cup fifth-round clash between England's two top teams turned out to be a one-sided affair on Saturday as Manchester United thumped 10-man Arsenal 4-0 at Old Trafford.

United were 3-0 up after 38 minutes through Wayne Rooney, Darren Fletcher and Nani as Arsenal's injury-hit side looked badly off the pace and short of motivation.

United, also without some leading players, were just as dominant after the break and Arsenal suffered a further setback five minutes after the restart when Emmanuel Eboue was sent off for a wild challenge on Patrice Evra.

Both teams then made substitutions to rest players for midweek Champions League games but United remained on top and got the fourth with another Fletcher header after 74 minutes.
