Manchester United have not started the Premier League season well. Solskjaer's side are not capable of keeping a clean sheet. Against Southampton, they conceded again thanks to Vestergaard's header.
Man Utd are struggling to keep a clean sheet. Despite the flattering scoreline against Chelsea, Man Utd are not proving to be reliable in defence. And against Southampton, De Gea had to pick the ball out of his net again.
Despite a punch away by De Gea, the truth is that the United defence could not clear the ball from the area. That was precisely what the Saints took advantage of.
Vestergaard was the one who drew Saints level at St Mary's. The Southampton central defender beat Lindelof in the area on the edge of the six yard box to beat De Gea.
