London - Manchester United will face bitter rivals Manchester City in the FA Cup semi-finals if Alex Ferguson's team can win their quarter-final replay against Chelsea.
United learned the Cup draw had given them a potential Wembley showdown with City just minutes after being forced to settle for a frustrating 2-2 home draw against Chelsea, who recovered from two goals down to set up a replay at Stamford Bridge.
If United do go through to face City, 5-0 winners over Barnsley in their quarter-final on Saturday, it will be the third successive season the old enemies have met in the FA Cup.
They clashed in the 2011 semi-finals at Wembley, with Yaya Toure's goal giving City a 1-0 victory, while United were 3-2 winners in the third round at Eastlands last season.
In the other semi-final, Premier League strugglers Wigan, making their first ever appearance in the last four, will face Championship opposition in either Millwall or Blackburn, who face a replay at Ewood Park on Wednesday after sharing a 0-0 draw on Sunday.
Wigan reached the semi-finals with a surprise 3-0 win over Everton on Saturday and Latics chairman Dave Whelan revealed he may lead the team out himself if they face Blackburn at Wembley.
As a player, Whelan suffered a broken leg playing for Blackburn in the 1960 Cup final against Wolves and he would love to meet his old club at the English national stadium.
"The dream is there," Whelan told Sky Sports News. "All Blackburn have got to do now is get through the replay and my dream is on, I can go to Wembley and we can play against Blackburn.
"When you've been to Wembley and got what I got, a broken leg and Rovers went on to lose 3-0, it's very upsetting. I feel I've got unfinished business at Wembley.
"(Manager) Roberto (Martinez) has asked me to lead them out at Wembley and if we get Blackburn, I may just say yes."
Draw for the English FA Cup semi-finals made on Sunday:
Millwall or Blackburn v Wigan
Manchester United or Chelsea v Manchester City
Ties to be played at Wembley on the weekend of April 13/14.
