Man Utd could face Arsenal next
Manchester United will face the winners of the tie between Arsenal and Leyton Orient in the FA Cup quarter-finals, throwing up the possibility that the Premier League's top two sides could clash at Old Trafford.
The two great rivals last met in the competition when United defeated Arsenal 4-0 in the fifth round in February 2008, while they contested the final in 2005 when the Gunners won on penalties.
Arsenal could not beat League One Leyton Orient on Sunday afternoon and now face a replay, an extra game that they will not want as they fight on four fronts.
Birmingham, Arsenal's opponents in the Carling Cup final next weekend, will be pleased to have been handed a home draw against Bolton, who defeated Fulham on Sunday.
After hammering Notts County 5-0 on Sunday, Manchester City will face Everton or Championship side Reading if they can overcome Aston Villa in the fifth round.
The final tie sees Stoke host West Ham or Burnley, who play on Monday evening.
