Jamie Carragher mocks Manchester United boss, explains why he's delighted Rooney scored

Wayne Rooney scored for Manchester United and Liverpool legend Jamie Carragher is delighted, and here's why.

Jamie Carragher has suggested Wayne Rooney's return to the scoresheet could backfire on Manchester United.

The former Liverpool centre-back noted via Twitter that it could lull manager Louis van Gaal into a false sense of security that the club do have enough strikers, when the view from many fans is the opposite.

Van Gaal courted controversy earlier this week, reported by The BBC to have said he sees Marouane Fellaini as a striker.

Given the club's high profile failure to lure big name signings this summer, it seems like an unsatisfactory solution.

Carragher commented that Van Gaal would be more content not to make a move after seeing Rooney net.

Carragher raises a valid question, but there could be some method behind Van Gaal's comments, perhaps to strengthen United's negotiating position in the transfer market.

Perhaps the biggest lesson to come out of last night was not Wayne Rooney or Marouane Fellaini, but Javier Hernandez's poor showing.

The Mexican came off the bench and missed a penalty and a simple opportunity from six yards out.

Recognised as United's second choice striker, perhaps the further experimentation of seeing Fellaini up front is closer than ever.

Carragher be warned though - a Fellaini winner when the two sides meet in early September will see his message retweeted for eternity.
