...and Arsenal have a third! Mesut Ozil plays a fine pass through to catch the Galatasaray defence totally square, this time it's Alexis Sanchez who streams into space down the left and cuts inside to curl home from 15 yards. A rout.

Does anybody seriously believe that Danny Welbeck is in the same class as Thierry Henry? Few are.

But Welbeck is having a fine game, make no mistake about that. He is busy now to work back and nick the ball back in midfield...

Dazzler:, external Why are the Henry comparisons 'off-target'? Both came with underwhelming reputations, and were poorly used at previous clubs.

Galatasaray's best chances of a result may be getting this game called off as their fans rain down flares on to the Emirates pitch. There are at least five behind the goal and there is a stoppage as Gala keeper Fernando Muslera put his gloves to good use and clears them away.

Captain Wesley Sneijder runs over to call for calm - and he seems to get a good reception. Game on!

One of the best names in Europe? Geoffroy Serey Die plays a smart one-two inside the Liverpool area, sumps Jose Enrique on his backside with a bodyswerve and then warms the hands of Simon Mignolet with a stinging toe-poke.

Sophie Gayter:, external Welbeck will get 15-20 this season for Arsenal. His pace and movement are excellent, and his confidence will continue to grow.

Liam McColgan:, external Welbeck the new Henry? Probably too early for those shouts but what class finishes.

Felipe Melo should be off, a very heavy two-footed challenge on Alexis Sanchez and the Galatasaray man is incredibly lucky only to be booked. He has the neck to tell referee Gianluca Rocchi off too. Terrible tackle.

"That was all about Welbeck's pace and power and then a quality finish. It was just a long ball and it was who was quickest and strongest, and I have to say it again but he opened that body up again like Thierry Henry. He picked his spot fantastically well.

"He's been a provider at Manchester United and working really hard for the team. Now he's a centre-forward and he runs with that extra spring in his step. He thinks he's in a sweet shop with the number of chances he's getting.

"They have to be thinking about the head to head now and Arsenal want to win this by as many as they can. I want to see Mesut Ozil play to embarrass his opponent and it's set up for them to really take this on."

For the hat-trick?! No!

Danny Welbeck has another chance as a cross from the right lands at his feet 20 yards out, but he rather snatches at that one and it's right at the keeper.

The comparisons with Thierry Henry are quite frankly well off target but Danny Welbeck isn't! Like a certain Frenchman of yesteryear he takes advantage of some horrible defending to latch onto a back header, hold off the challenge of Felipe Melo and then confidently plant the shot across the keeper and into the bottom corner.

Excellent stuff from the England man. Arsenal in control.

Just like you and your mates at home on a Sunday morning, referee Jonas Eriksson has to remove some debris from the pitch. It's not a can of cider this time though, in fact I don't know what that is. It looked like a film cartridge from an old camera but I doubt anyone is going to need the dark room this evening.

On the pitch, the home side remain on top but they haven't yet tested Simon Mignolet.

Harry Bunn has fired Huddersfield into a 1-0 lead over Wolves, while Hugo Rodallega has done likewise for Fulham against fellow strugglers Bolton. Potentially a costly goal for Dougie Freedman.

Leeds v Reading is goalless.

Cristiano Ronaldo has now scored from the penalty spot - blushes saved for Real?

Danny Welbeck's movement off the shoulder of the last defender has been impressive since he joined Arsenal and that was evident again as he opened the scoring. How many can he get this season?

"That came from one end of the pitch to another, Alexis Sanchez was nice and free and it was a lovely ball. Welbeck came through like Thierry Henry to poke it into the corner.

"He opened his body up and the ball didn't get there quick enough so he prodded at it but the goalkeeper should do better."

Megs! Alexis Sanchez drives in from the left and picks out a fine run from Danny Welbeck. The Arsenal striker beats the offside trap with an arced movement and is able to let the ball run right across him and on to his right foot before he pokes through Fernando Muslera's legs.

Antoine:, external Re: David via text, at least they are actually the Champions of their league. More than Liverpool, Chelsea or even Barca can say.

Jacob Mignano:, external Re 1950: It's almost as though Ludogorets read David's text message.

Sam Tipton:, external Dave you are wrong my friend. They have earned their place in the Champions League and always put up a fight.

Liverpool look very shaky at the back as both full-backs get caught on the ball in quick succession, but they possess plenty of pace at the other end of the pitch. Lazar Markovic burns down the right and eventually picks out Raheem Sterling on the left but his final ball is not up to much.

They need a goal to settle down.
