MU's test of nerve

A week may be a long time in football and if Manchester United take anything less than maximum points against Aston Villa this weekend it is going to feel like an eternity.
Last Sunday, pundits unanimously declared the Premier League title race to be over after Manchester City slumped to defeat at Arsenal, a loss which left Roberto Mancini's men eight points adrift of United with six games left.
But United's hitherto serene progress towards a 20th league crown was rudely interrupted in the form of a shock 1-0 defeat at Wigan in midweek, a reverse which cut their lead at the top of the table to five points.
Just as significantly, City's thumping 4-0 win over West Brom means Mancini's side have now taken a handy advantage over United in terms of goal difference.
With United still to face City at Eastlands on April 30, the Wigan loss means Sir Alex Ferguson's side now have precious little margin for error -- provided of course that Mancini's side can keep on winning.
City have the opportunity to put pressure on United by cutting their lead to two points with victory at Norwich on Saturday.
