The two Manchester sides, first and second in the Premier League, were kept apart in the draw for the quarter-finals of the FA Cup. But should United defeat Reading on Monday night and Chelsea win their rescheduled fifth-round game at Middlesbrough on 27 February, the two will meet in the tie of the round.
Blackburn have been rewarded for their win at Arsenal with a trip to Millwall while Barnsley, the other non-Premier League side definitely through to the last eight, face a daunting visit to Manchester City, winners of the trophy in 2011. The winners of the Goodison Park replay between Everton and Oldham Athletic will play at home to Wigan Athletic.
