Sir Alex Ferguson says United's seventh straight Premiership win is due to the patience of his players and Wayne Rooney's ability to deliver under pressure.

Here are the manager's post-match quotes, from an interview with MUTV's Steve Bower.

Tough opposition
"Sheffield United set up a system to make sure it was going to be difficult for us and they proved that. I think the important thing is that we kept our patience, we kept probing, we made some good chances in the match. I was hoping we'd get a goal before half-time, because I felt that if we'd gone in 1-0 down, it was going to be a long road back. I think they would have been more entrenched. I think the equaliser gave us a bit of patience to wait and wait and eventually we got there."

Waiting game
"You always hope that by being patient and using the skill we have - I thought that Scholes and Carrick totally controlled that area of the field and kept the probing going - there was always a possibility that we'd make the chance that mattered. The goal came from an unusual source really, a long ball to the back post is not the way we'd normally score a goal, but we're grateful for it. It was a marvellous finish from Wayne Rooney."

Missed opportunities
"We're winning matches. We can always look back and say we were maybe a bit careless with our finishing at times but it's more important to win these difficult away games."
