Wayne Rooney's wonder goal boosts United's title hopes, but kill off City's chance of finishing the season at the top of the league.
Rooney scored with an amazing over head kick to win the Manchester Derby 2-1 against the blue side of the city.
Rooney was able to latch on to the end of a looping Nani cross to put United back into the lead after 78 minutes. Joe Hart didn't move as the ball headed straight for the top corner.

Known for his goal scoring ability, it is shocking that this was only Rooney's fifth goal of the season's campaign.
This derby didn't have the tension it usually does before the game. Instead, United old boy, Ryan Giggs, praised former Red Devil Carlos Tevez.
City must feel hard done, as for large parts of the first half, they seemed to be on top.
It took more than half an hour for United to get a meaningful save out of Hart.
Five minutes before halftime, City went one down thanks to a Nani goal, which was passed into the net just out of reach of the keeper's outstretched arm and leg.
It took City's millions to peg back the difference. It was only when the 27 million pound man Edin Dzeko came on that they finally scored.
Even City boss Roberto Mancini said they were lucky with their equaliser. Dzeko's shot was going well wide before it hit the back of Silva, which deflected it towards goal and wrong footing Van Der Sar.
Then it was time for "that shot."
Nani looped in a cross, which Rooney caught perfectly. It flew past Hart and straight into the top corner.
After the game, Rooney said, "I saw the ball come into the box and I thought 'why not?'"
