Nemanja Vidic wants Manchester United to improve their defensive record on the road.
The Red Devils have conceded seven goals in three matches away from Old Trafford and although they have scored seven as well, Vidic wants the defence to improve if the team is to mount a serious title challenge.
"It is a big concern that we are conceding so many away goals," said Vidic. "We have to stop doing it. We cannot let it happen again.
"Over the last few years we haven't given that many goals away or even allowed them so many chances.
"Before we have always looked strong, so this is not what we are used to. We have to play much better in our away games."
