Sir Alex Ferguson says Manchester United are four wins away from lifting the Premier League title.

Ferguson has set a four-win target to clinch his 13th Premier League championship as manager of Manchester United after their 1-0 success at Sunderland.

"We have to win four games now, I think, but it's important to focus on our next league match, which is Manchester City at home," said Sir Alex. "It was important to win today because we go into the City game next Monday with a 15-point lead."
