Manchester United made the trip to Sunderland knowing that a victory would open up an 18-point advantage over rivals Manchester City at the top of the Premier League table.
As it was, an own goal from Titus Bramble, who diverted a shot from Robin van Persie into the Sunderland net was enough for the visitors to claim all three points at the Stadium of Light.

"We've looked at the issue of tiredness. Wayne Rooney came back pretty tired. It's always difficult when there is a short space of time between games. Today is important to us. Our priority is to win the Premier League."
"It's a big game and hopefully we can get a result. The boys will be ready to go," he told the club's official website.
"Manchester United aren't going to be complacent, not at all. They'll be focused on the game and looking to make sure there's no chance of Man City catching up. But we need points too and that starts on Saturday.
"We've just got to work and play as a team. We have the ability, it's just up to us to make sure we stick together and work hard."
"It has been an extremely comfortable 45 minutes for Manchester United. Sunderland are suffering a lack of confidence and are playing well below the standard I know they can play. They have not given the home crowd enough and if I was Martin O'Neill I would really lay into them at half-time and say come on 'let's have some real passion'."
"Sunderland aren't going forward. It's winding me up and I don't even want them to win."
