Alex Ferguson has praised his players for clawing their way back to title contention.
Manchester City have led the Premier League for most of this season, but are now level on points with local rivals United.
"I have to congratulate the players on achieving the position we're in because of the injuries we've had," Ferguson said.
"They've shown resilience and we're in the position we are now because of that.
"I was hoping City would drop something but I also knew we really had to perform well to take advantage."
United could move three points clear of City if they beat Fulham tonight.
