Manchester United recorded their first win of the Premier League season when Darren Fletcher's scruffy first-half goal secured a 1-0 triumph at Portsmouth.

Fletcher was credited with turning the ball in from Patrice Evra's cross in the 32nd minute although Portsmouth defender Sylvain Distin appeared to make contact with the ball and Sol Campbell also got a touch in a vain attempt to keep it out.

It was the second goal in as many games for the Scotland midfielder after he also found the net in last week's draw with Newcastle United.

Wayne Rooney beat Portsmouth keeper David James with a shot early in the second half but had the effort ruled out for offside.

For FA Cup holders Portsmouth, defeat continued their unhappy start to the season after losing the Community Shield to United on penalties and their league opener 4-0 at Chelsea.
