Manchester United forward Wayne Rooney has insisted that his side need to improve on their defending.

United sit top of the Premier League table after coming from behind to beat Queens Park Rangers 3-1 at Old Trafford on Saturday.

However, having lost three games and conceded 18 goals so far this season, Rooney believes that the Red Devils need to improve their form at the back.

"Clean sheets are the foundation we hope for, we know we have players who can score goals and win us games," said Rooney. "If we can get a clean sheet, then I'm sure we can get them at the other end and win games.

"As a team, we've played some good stuff at times but we've also ground results out as well. To lose three games this early is something we need to put right.

"We're lucky that we've won all the other games and not drawn any. It means we're still in a good position in the league. So we need to make sure we are full focused now and try to kick on, try to go on a good run."

United host West Ham United in their next match on Wednesday.
