January 5, 1991: Chelsea 1, Oxford United 3

OXFORD United staged a memorable upset as they dumped Division One side Chelsea out of the FA Cup.

Brian Horton's men were clear underdogs heading into the third round tie, with the visitors 17th in the second tier despite a recent upturn in form that had seen them go four matches unbeaten.

Chelsea, meanwhile, were eighth in the top division and had lost just one league game at home all season.

But United held their own against Bobby Campbell's side and took the lead just before the break, Lee Nogan the man to make it 1-0.

Any indication that the U's did not deserve their lead was dashed ten minutes after the restart, when John Durnin scored for the fourth game in succession to increase their advantage.

Kerry Dixon pulled a goal back to set up a tense finale, but as on so many occasions in 1990/91 United turned to Jim Magilton.

The Northern Irishman struck late on to restore the two-goal lead and send the U's into the fourth round, where they lost 4-2 at Tottenham Hotspur.

But the win at Chelsea was an important part of United's improvement in the second half of the season, as they lost just four more Division Two games to finish tenth.
