MANCHESTER - A week could be a season's worth of difference for Manchester United.
Last Sunday, a flat United side was run ragged by Manchester City.
But on Saturday in the fifth round of the English FA Cup, United were nothing like the team that capitulated to their cross-town rivals.
A 4-0 thumping of Arsenal, their fiercest Premier League title challengers, was completed with verve and confidence.
Other results: Bristol Rovers 1, Southampton 0; Cardiff 2, Wolves 0; Chelsea 3, Huddersfield 1; Coventry 0, West Bromwich Albion 5; Liverpool 1, Barnsley 2. - Sapa-AP
