LONDON (AFP) - Manchester United and Chelsea were kept apart in Monday's FA Cup semi-final draw but must play tricky replays before a possible final meeting at the brand new Wembley stadium.

Blackburn have been drawn against the winner of the scheduled replay between Chelsea and Tottenham after they drew 3-3 at the weekend.

Watford will play Middlesbrough or Manchester United in their last four fixture and the neutral venues for the April 14/15 matches are yet to be decided.

Blackburn chairman John Williams was happy with the outcome, telling Sky Sports News: "We are happy. You take what comes - if you are going to win it you have to beat everyone along the way."

Blackburn have knocked out Everton, Luton, Arsenal, and then Manchester City at the weekend, on their way to the last four.

"We played well (against City). We restricted City to very few attempts and deserved to win," Williams added.
