Man Utd star who is 'causing Ole Gunnar Solskjaer a problem' identified

Danny Murphy says David de Gea's recent poor form is causing Ole Gunnar Solskjaer and Manchester United problems.
The Spain international keeper, who has yet to pen a new deal with the Red Devils, has been the club's most consistent performer over the past few years.
But his recent form has left much to be desired, with a number of uncharacteristic errors costing Manchester United dearly in the top four run-in last season.
De Gea was poor in Manchester United's shock defeat by Crystal Palace at Old Trafford on the weekend, and Murphy is convinced something isn't right at the club.
 
"The worrying thing for United, a couple of worrying things, De Gea again," Murphy told talkSPORT.
"He should have saved the winner comfortably, another mistake. It's happening too often. We know how good he can be but there's something not right and that is a problem for United."
In addition to sorting out the problem in goal, Murphy believes Manchester United need to strengthen in midfield and sign a player in the mould of Michael Carrick.
