It should be 2-0 but David De Gea makes an excellent save to deny Edin Dzeko after more poor defending. United then break - much to the home crowd's pleasure - but City manage to clear.

Tim Krul denies Romelu Lukaku with a smart save with his feet. The Belgian should have done better though from Leon Osman's clever through ball.

A real slow-motion grimace-fest of a collision at Old Trafford. Danny Welbeck, being pursued by Fernandinho, slips as he chases the ball and clatters into Pablo Zabaleta. It looked very ugly, but replays show there was nothing malicious in there.

Welbeck is booked by Michael Oliver.

Not much to report at the moment - Everton have won a couple of corners but nothing in the way of clear openings.

"Arsenal came out with a real intent to go at Swansea right from the start in this game, Oxlade-Chamberlain had a fantastic shot and they could have been ahead.

"But it was a magnificent goal from Wilfried Bony - Neil Taylor ran in to the Arsenal half with all the time in the world. He sent the cross in to the box and Bony planted a fantastic header in to the corner. Taylor just picked Bony out at will, it was a fabulous header."

A flurry of early goals in the Championship!

Third-placed Derby get off to a flyer at Ipswich, with on-loan Chelsea man Patrick Bamford putting them ahead in the first minute. Leeds' difficult week continues as they concede a second-minute goal at Bournemouth, while Huddersfield and Middlesbrough are locked at 1-1 already.

"United just cannot get near the blue shirts of Manchester City. The movement of Silva is superb and at the moment he is running the game. People think why does Silva always get the ball first, because he anticipates everything."

Simple, but beautiful. Neil Taylor's curling delivery from the left is met by a sky-scraping Wilfried Bony who directs a precise header past a rooted Woiciech Szczesny. That is his 20th of the season.

Manchester United are still swaying on the ropes. Michael Carrick cheaply gives away possession and David Silva swoops, driving in on goal and Phil Jones only just manages to knock him out of his stride as he threatens to pull the trigger.

Antonio Valencia looks like he is being readied to come on.

Usama Zafar:, external I think we should concede our both legs against Bayern. A 6-nil aggregate might be less than what we will actually concede

Manchester City are popping the ball around and Manchester United look a couple of yards slower in thought and deed. They haven't laid a glove on City yet.

BBC Sport chief football writer Phil McNulty at Old Trafford:

"Manchester City manager Manuel Pellegrini is in his technical area waving his team forward - fair to say they've not needed much encouragement so far."

It looks like David Moyes may be about to change things up already. Darren Fletcher is going through an extensive warm-up and there are no signs of an injury among his team-mates on the pitch.

Alex Oxlade-Chamberlain (or is it Kieran Gibbs?) strikes a firm effort from the edge of the area but Michel Vorm is comfortably behind it. Quite a few empty seats at the Emirates.

Mehran Ebrahami:, external This is going to be a long game!

Ed Gutteridge:, external No, no. Not fair. We weren't ready. Ref, restart please.

"You're at home, playing your local rivals who we know are fantastic. So from the kick-off you go and press them, but they just let City do what they want and it was a simple tap in.

"City are all looking for the ball and United, with their three in midfield are not yet closing down. I think there's a fear factor."

Newcastle have started brightly on Tyneside with Sylvain Distin required to dive in to block Yoan Goufran's well-hit effort from inside the six-yard box.

The title is heading very much in the direction of Munich.

Manchester City have blitzed United straight from the kick-off. Rafael needed a last-ditch tackle to block David Silva's burst into the box, Samir Nasri rifled against the post and finally Edin Dzeko pops up to side-foot home the rebound.

United shoulders slump with just forty-eight seconds on the clock.
