I'm afraid our time is up and I'm going to have to exit this webchat. Thanks for all your questions, even the rubbish ones, and sorry I didn't get to answer all of them. Enjoy the games tonight. And stop staring at Jurgen Klopp in *that* way. Bye. Barney

I wrote a book about this you know. It's called The Manager and it's available in all good charity shops, prison libraries and far eastern landfill sites. I think basically there's quite a lot to it.

Bayern last year were the best. England at times the worst. Like a middle aged man in skinny jeans

I agree with the poster below - when the time is right some old-fashioned set piece stuff and crosses in the air. Olivier Giroud very deliberately roughed up the Dortmund centre backs at the Emirates and at times it seemed to work. It is very hard to say, oh sit back and let them have the ball: this is a very high risk strategy and one that makes you look quite silly when it doesn't work. But it's true that playing at speed on he break is probably the best bet. Remember Arjen Robben at Wembley in the summer. Exposed a lack of covering speed at times. Plus also Dortmund aren't a team who does it all the time. They have lows, even in a game, moments in between those heavy metal solos. Arsenal had their moments in the first match.

It's an odd one with Fellaini isn't it? I'd say the one thing he's genuinely exceptional at, better than any other midfielder, is playing with his back to goal as a kind of forward pass conductor, using that brilliant chest control - like Puskas' left foot, he has a chest "like a hand" - to disturb defenders and link play. That's what he's brilliant at, that's what got him noticed, that's what basically got him a move to United.

But now he's there he's never going to be allowed to play like that again because it's too primitive and no one would put up with it.

So he has to do all the other stuff instead like passing and running and positioning that he's only so-so at. I think it's called rising to your level of incompetence.

No I don't think so. This is the argument often put forward that some oil-rich goon splurging vats amounts of cash around distorting other club;s carefully laid recruitment and player-devlopment programmes are in fact a kind of footballing Robin Hood, saving us from Those Other Teams Who Are Already Rich. But it's rare to see it being doing in a way that makes sense. Generally speaking Man Utd, Bayern Barca etc are rich because of decades of success combined with planning and building and commercial good sense (yes Bayern inherited a stadium). You can't begrudge them that - it is how the world works. But the other way, the ambassadorial carbon-state project, the oligarch's pet club ... It's not my idea of sport.

No, definitely not. It's now or never. Not impossible though. I think that could be the game of the night.

I thought they were all right, but the could-have-won-it-1-0 theory does hide the fact that perhaps this was a game they should have wrapped up in the first half. Then again, Moyes is new to all this and United will qualify from this group, probably thanks to that point. Plus, Kagawa looked OK in two different positions. I read recently the problem with Shinji is just that whole team isn't set up to play to his strengths. Just do that and he'll be fine. But that's not the way it should be with a high class player. He's got to be better than that, not some latter day Le Tissier of the East

I find myself in the odd position of absolutely loving the Champions League, despite on the face of it hating what it stands for, the stratificaiton of football, the endless TV-led wringing out of the product etc etc. The problem is for all that it's just brilliant. Not so long ago there was basically no football on TV. Now there's... this. It is - quietly - quite amazing

I love him too much. He... completes me. In fact I'm not sure where he ends and I begin.

It's all getting a bit much isn't it? The team, the style, the loyalty, the eloquence, the magnanimity, the rumpled good looks, the magnetism. Actually cancel all that I think I slightly hate him.

The Bayern Supremacy is only just beginning. They're not finished with us just yet. But I'm not a betting person. It's all a mystery to me. Just like fantasy football, I secretly suspect it's one of those things you do when you're not really that interested in the actual game. Like arguing about referees. And being offended and all the rest of it.

I'd prefer the voice of Dean Martin in Guy and Dolls. The bit where he says "If you see a Joe spending half of his dough..." in a rat-pack ish kind of drawl. So can you just do that instead from now on.

With Mikel Arteta I guess, or fialing that a small robot that runs around quite slowly pointing at people and shouting. Flamini has been good but let's not go overboard. Arsenal's attacking fluency has made it easier than it might. This would have been a real test for him, big shame he's out hope those old niggly problems not coming back.

Bale and Ronaldo, it feels like an occupational hazard of running around getting fouled a lot. The real problem with Young is that he rarely tries to beat a player, certainly rarely does it. What he tries to do is earn a foul by shifting his feet quickly. So it's only going to end one way: foul or dive. This just feels very cynical and pointless. It is a tick though. I'm not sure he can stop himself or that he's really thinking about it. Perhaps we could trace this back to one traumatically defining episode - the trip that won the penalty that won the game that won the praise that won the new contract that bought the horrible new car etc etc. Or maybe some kind of electric shock aversion therapy. Either way it's time to condemn a little less and understand a little more. This is good for nobody. He should have been a better player than this.

He is isn't he? Not often the bulkier type of striker has charisma too. He's like Emile Heskey with goals and a makeover

Not really, I think the fact Dortmund are very very good might be the key factor. Plus of course they're extra hard to beat at home. Also, Mikel Arteta was very good in the same role against (hang on...) Liverpool at the weekend... Well, you know what I mean. Not quite the same given Liverpool have one of the more low pressure midfields whereas Dortmund are like a pack of rabid dogs. But still. Arsenal will need to keep the ball rather than defend like Trojans (they will also have to do that) to get a result. Who knows, the absence of Flamini might even be a blessing. Pass, attack, play going forwards. There you go. 3-1 Arsenal. Thank you and good night

Chelsea two years ago.

I think Arsenal will qualify. The only note of alarm so far is a 2-1 home defeat to Dortmund who were just a little bit better, as expected. It's just about finishing ahead of Napoli and with that in mind I even think Arsenal might get just, just, somehow, just a draw tonight which would probably make the difference. Somehow the idea of Arsene Wenger in the Europa League just feels a bit wrong, like Prince William somehow being forced to get on a bus. I don't think it will come to that though. Two well placed draws from here and a low key exit at the hands of A European Giant in the next phase awaits. Glory glory!
