The weekends FA Cup semi-finals saw both Chelsea and Manchester United progress to the Wembley final - but not without a scare along the way.

United saw EPL bottom club equalise at 1-1 before they eventually ran out 4-1 winners, with Rooney and Ronaldo again on the scoresheet. Meanwhile, Chelsea again left it late before progressing with an extra-time goal from Michael Ballack to run out 2-1 winners over Blackburn at Old Trafford.

So, as expected (and hoped by the FA I'm sure) Chelsea face off against United on May 19th which could be sandwiched in between their EPL showdown in the penultimate game of the season, and a possible Champions League final encounter if the two sides progress against Liverpool and Milan respectively.

It is now set for an intriguing final month of the season as the two sides - neck and neck throughout, head towards a thrilling climax.

United are chasing a repeat of their 1999 treble, whilst Chelsea are chasing an unprecedented quadruple - having already claimed this seasons Carling Cup. It would be quite a feat for either side to win every available trophy but the one thing both sides possess in abundance is the desire to win, and neither manager will let up an inch in their quest for dominance over the other.

In the EPL, United hold the advantage - as they have done most of the season, due to their three-point lead and slightly more favourable run-in, but if Chelsea can keep pace with them (or even claw a point or two back) then they will have to in their hands when it comes to their showdown at Stamford Bridge in the last week of the season.

In the FA Cup, United hold the pedigree in terms of FA Cup appearances and wins and this is a difficult one to call as so much could depend on who wins the EPL (the week before) and on who reaches the Champions League final.

Which leaves the Champions League. Both sides I believe are favourites to progress - United slightly more so, but will have to be wary of their opponents Liverpool and Milan - whose remaining hopes of silverware rests with the Champions League.

Chelsea, having been hit with injuries this season are now beginning to get players back and their fitness levels are unparallelled in the EPL, and they look to be beginning to peak at this crucial stage of the season. United, relatively untroubled by injury have succumbed of late to injuries to Vidic, Silvestre and Ferdinand, but shrugged these off in their recent defeats of Roma and Watford.

As we head into the final month of the season, what is usually a tense and crucial time of the season has been magnified tenfold by the set of circumstances which now could see them face off three teams in less than two weeks to decide the battle for supremacy in the 2006/07 season.

An intriguing fight lies ahead, and whatever the final outcome is, there are certain to be a number of twists and turns remaining between now and the middle of May.
