Guillermo Varela has to stoop and clear an excellent cross from Tom Ince as Derby step up their pressure. Manchester United have Michael Carrick warming up. 

Chelsea confirm the long-mooted signing on Brazil forward Alexandre Pato.

One of the rising stars of world football. In 2007.

Derby have a half-hearted penalty appeal waved away as Morgan Schneiderlin and Chris Smalling mark up at a corner, very tightly. Derby still have plenty of time to rescue this. 

Shaun Farrelly: Can imagine Louis van Gaal being unhappy with Daley Blind for being out of position when he scored.

Adam Latham: Blind gave up waiting for a striker to get into the box so did it himself!

Daley Blind was the furthest forward in open play as he put Manchester United back in front.

"I'm not sure what Daley Blind is doing in the box - but what a finish when he gets there. Nobody tracks him and he finished it like a striker. The goal had been coming."

Open is one word for Derby's approach at the moment - ragged I would say. All shape has been lost as Manchester United look to pick them off. There has been some superb last-gasp defending though.

"Derby can't play the remainder of the half like this - they are too open.

"They need to stop making silly mistakes. They have given the ball away six or seven times already this half."

Who wouldn't want to hear that?

The rain is really coming down now as Manchester United catch Derby napping with a quick corner, Daley Blind hits it across goal, it deflects around, penalty-area bagatelle, and somehow the Rams get it away from Juan Mata...

Mr Pigeon, Scotland: Watching Manchester United this season could be perfectly accompanied by the Benny Hill music, played by drunk musicians who keep falling over and dropping their instruments. 

Perhaps Derby need to get their full-backs bombing down those flanks more often. Our average position graphic shows that the home side (left) have been very compact, with only Cyrus Christie (2) finding any space out wide.

United, on the right, have plenty of width with Anthony Martial (9) offering the most attacking threat.

First roll of the dice from Paul Clement. Nick Blackman comes off and on comes new signing Abdoul Camara. 

The game really opening up now, surely more goals in this?! Jesse Lingard crosses from the right, it flicks up off the heel of a defender and Juan Mata is there to meet it. Can he steer in his header? No, just wide! 

Chris Smalling starts a neat move which pitches up at Anthony Martial's door on the left. You know what's coming, he glides away from his man again and this time is able to find Wayne Rooney. Rooney swivels and shoots but Richard Keogh makes a fine block!

Jacob Butterfield then breaks through the middle, it parts for him - and he takes the wrong decision!

Stephen Warnock skis into a challenge and catches Guillermo Varela, that was late and hard.

"That was a bit rash but I don't mind that," says Danny Murphy. Let them know you're there etc...

Jamie Evans: Martial is doing whatever he wants to that Derby right back, gliding past him every single time!

That's what Cyrus Christie offers going forwards though! What a cross from the Derby right-back, whipped in at terrific pace, it beats Chris Smalling all ends up and Tom Ince is there to finish! But he can't quite reach it...

Have Manchester United identified Derby right-back Cyrus Christie as a weak link? They're certainly getting plenty of the ball to Anthony Martial on that left flank. Almost half of their attacking play is going down that side, meaning Christie is having a tough shift.

Manchester United have started the second half in the same manner they started the first. Swarming over Derby and looking a threat.

Derby do counter well now and Nick Blackman wins a corner. Will set-pieces be key?
