It's good to see you're still as lacking in a sense of humour and as unable to take criticism as ever.
You went from complaining about how we have such a short team to immediately proclaiming we'd lose to Barcelona. Forgive me if I naturally assume that the two points must be related, because you're not exactly known for your clarity of posting. I just thought it was rather amusing that you seemed to be saying we were too short to beat one of the only teams smaller than us.
As for your idea of playing 4-4-2 and lumping it down the wings, I'm not sure where to start. Perhaps your strange assumption that nobody has tried a 4-4-2 against Barca yet, and that they'll be therefore completely unaccustomed to it? Or the fact that you repeatedly say we don't have any wingers in the squad, and yet think that somehow the team will transfer to a formation with wingers fine? Or the idea that Maxwell and Alves aren't fast enough to deal with a quick winger formation? Or that conceding a player in the middle, against a team who love to get forward and apss it through teams, will work? Especially when said player will most likely be replaced by the workaholic Nicklas Bendtner in your quest for "punt it long, cross it in" glory? Never mind Big Sam, are you Martin O'Neill?
How do
I think Arsenal should play against Barcelona? Well generally, I reckon the formation that we're most comfortable with, using our best players, would be better than foolishly abandoning it in search of kick and rush silliness. Wilshere and Song doing their best to deny Iniesta and Xavi the time to work their magic. Fabregas pushing up into Busquets' territory, so there's no easy out for the team when they need it. Nasri giving Alves serious food for thought on the left. RvP troubling a very high back line.
Will it work? Probably not, but that's more to do with the fact that Barcelona are just so damned good at the moment, and also that we're far more likely to lose because of a back line mix-up or failure to cover (something which we did against Ipswich frequently, thank you for pointing that out), than how many wingers we play.
Cheer up DM, you don't always have to get itchy for a fight when I disagree with you.
