Premiership heavyweights Manchester United and Chelsea could be set for a dramatic FA Cup final meeting at the new Wembley Stadium after being kept apart in the semi-final draw.

Both teams must overcome tricky replays before confirming their place in the last four with Chelsea meeting Tottenham at White Hart Lane and United facing Middlesbrough at home.

Blackburn will play the winner of Chelsea against Spurs and the top flight's bottom club Watford have been drawn against United or Boro.

The ties will be played on the weekend of April 14th and 15th. Venues are to be announced.

Blackburn chairman John Williams insisted he was pleased to have been drawn against Chelsea or Tottenham in the FA Cup semi-finals.

Rovers made it through to the last four with yesterday's 2-0 victory over Manchester City at Ewood Park.

"We are happy. You take what comes — if you are going to win it you have to beat everyone along the way," Williams told Sky Sports.

Williams also insisted Rovers deserved their place in the semis having already disposed of Everton, Luton, Arsenal and City.

"We played well (against City). We restricted City to very few attempts and deserved to win," he added. "We've had a hard run so we deserve to be there and let's hope we can go one better."

Watford chief executive Mark Ashton insisted the Hornets were "delighted" to be in the semi-finals although their joy will be tempered by the news that goalkeeper Ben Foster would be unable to face his parent club Manchester United should they win through.

Ashton told Sky Sports News: "Any draw in the semi-final is a good draw and we're delighted to be there.

"It's fair to say we are the team everyone wanted to play. we are delighted to be there and will be giving it our all."

However, with Foster on a season-long loan from Old Trafford, Ashton revealed: "We have an agreement with Manchester United that Ben wouldn't play in any competition this season, so as far as we are aware that will stand."
