Ronaldo tries an extravagant overhead kick on the edge of the box and although he connects with it, it is straight at Cech.

Superb defending from Wayne Rooney as he flicks the ball away from the head of Drogba at the far post for a corner.

A we enter three minutes of injury time here at the Bridge you get the feeling somebody is going to get a chance - but who?

It's end to end stuff now with both sides looking to grab the winner - will either of them be rewarded?

Superb block from Alex! United break with lightning pace but Fletcher's shot is blocked by the Brazilian who threw his chest at the ball bravely.

The force is really with Chelsea after that goal and if their is a winner in this game then they look most likely to get it.

Kalou almost gets a second immediately as Gary Neville's poor clearance drops to him but United's captain is there to deflect it over.

Now it should probably be 2-0! Fletcher releases Ronaldo down the left and he returns the favour for Rooney at the far post but the England striker can't direct his shot inside the post.

Almost a chance for Ronaldo as Rooney curls a super ball to the back post but the Portuguese is up a little early and can't make proper contact with his head.

And again for Anelka! Joe Cole fires a low ball across the box and Anelka has an open net but he cna only direct it out of the danger area.

Chance for Anelka but again its a poor finish. Bosingwa does well to beat Evra down the right flank and chips a clever ball into the six yard box but the Frenchman skews it wide.

For the first time in the half United's back four get some light relief as they apply a bit of pressure on the Chelsea goal - but no real goalscoring chance comes from it.

Another waste from Joe Cole! He beats the offside trap but fires straight at Kuszczak from close range and United are let off but the goal is surely coming now for the hosts.

Michael Ballack has just saved Gary Neville from a red card - the United captain slides in recklessly but Ballack stays on his feet when a second yellow card would have followed a free-kick.

One criticism of the official today is that he has tended to penalise any form of contact and now the players are becoming annoyed by it a little.

No doubt now that the change has opened things up again now as Ronaldo breaks on Chelsea before Anelka breaks back on United.

The big question now it seems is will Ronaldo chase Ashley Cole back towards his own goal or not? If he doesn't then Chelsea have a little opening possibly.

Clever from Joe Cole who delivers a little curler from deep towards the penalty spot and Drgoba is just about eased out of it by Ferdinand.

Chelsea have used what would be called there 'big name' substitute and it appears that United are preparing to respond as Ronaldo readies himself for action.

Chelsea are employing an interesting little tactic at the start of the second half as Drogba is trying to get himself in a height mis-match with Evra everytime the ball is on the left flank.

Joe Cole wastes a superb chance to get the Blues level as he fails to connect properly with Anelka's cutback and Evans is able to clear.

Drogba is on now at last to try and ruffle a few Manchester United feathers in defence.

Didier Drogba is going through a vigorous set of warm-up exercises during the interval - could he be about to come on to give Chelsea another dimension in attack?

Ballack tries his luck from range now but Kuszczak makes a pretty standard save this time.

United should lead 2-0 but they don't as Berbatov's pass to Park is a little lazy and the chance is gone - superb work from Rooney though to rob Terry in the build-up.

There are going to be three minutes of time added on for stoppages.

As the break approaches tempers are starting to fray a little as Chelsea grow frustrated and United are heavily under pressure.

Poor officiating from the linesman as Anelka is clearly offside but is allowed to run through on goal only to slice over the bar.

Finally Chelsea test Tomasz Kuszczak from range through Alex and he fumbles but Rio Ferdinand is alert to clear out for a corner.

Chelsea are looking pretty good in midfield at the moment but the final ball is letting them down. Eventuall though they will get one right.

How much longer will Paul Scholes last? Moments after being booked he accidentally handles and then flicks the ball away - some may have booked him again.

The Blues are really asking questions of the United defensive unit now and you have a feeling that the equaliser could be on the way before the break.

The United keeper has a lot of problems as he now fumbles a 'bread and butter' ball almost into the path of Joe Cole - and he is now being replaced by hte looks of things.

The home support are again unhappy as they want a red card for Owen Hargreaves - ambitious shouts from the crowd but a free-kick is given for the hand-off on Ashley Cole.

The fans want a penalty as Neville sells Van Der Sar short, who just gets a finger to the ball but gets plenty of Malouda too - nothing given, but the keeper is down.

Chelsea are enjoying a little period of possession in the United half at the moment and the visitors are unable to get the ball back - but can they create a chance?

Edwin Van Der Sar was shaky - at best - at Anfield and concerns over his form are not eased as he flaps at a Lampard corner - fortunately for him nobody in blue is following in.

What a save from Cech! Rooney attracts Alex and Terry but has support from Rio Ferdinand of all people who is denied by Cech who makes up for that earlier error.

There is a fear from the Chelsea bench that Carvalho could have some knee ligament damage, which would be very bad news - Alex has settled in seamlessly though.

More problems for Chelsea as Alex is readying himself on the bench, so somebody must be carrying a knock.

This is shaping up to be a cracker! Joe Cole beats Evra (possibly courtesy of a hand but nothing is given) and with Van Der Sar beaten his slices into the side netting.

Petr Cech is almost incredibly embarassed! The keeper races from his area but loops it straight to Berbatov whose effort is directed goalwards by Rooney but it bounces 6inches wide.

First chance and it goes to the visitors! Hargreaves delivers a delightful ball in and Fletcher is on the scene again - he should probably have scored that time to be fair but it bobbles a fraction wide.

Chelsea look relatively unconcerned though and are quickly passing the ball about between themselves at the back and attempting to assert pressure of their own.

United off to a very bright start and Fletcher hits a speculative half-volley from the edge of the box, but it strikes Berbatov on its wway and comes out.
