Manchester United will face Chelsea if both clubs progress through their respective fifth-round ties. Chelsea, the defending champions who are looking to win the competition for a fourth time in five years, will face npower Championship side Middlesbrough next.
The winner of that tie will then play either runaway Barclays Premier League leaders United or Reading in the quarter-finals, with those teams playing their fifth-round clash at Old Trafford on Monday night.
Blackburn's reward for their shock 1-0 victory over Arsenal at the Emirates Stadiumwas an away tie with fellow Championship side Millwall, who ended the run of non-league Luton in the fifth round with a 3-0 triumph.
The other quarter-final will see Wigan, 4-1 victors over Huddersfield, travel to either Oldham or Everton.
League One Oldham, the lowest-ranked side still in the tournament, earned a fifth-round replay with Everton at Goodison Park after Matt Smith scored a stoppage-time equaliser in a 2-2 draw.
The quarter-final ties will be played on the weekend of March 9 and 10.
