They've got some special players, but they've also got some big weaknesses and some very average players (relatively speaking). Their forward line is about as uninspiring as ours, for example. In fact, Walcott and Podolski are probably of a higher calibre than Vucinic, Matri, Quagmire etc. They don't play with a 10, but I reckon they'd find a spot for Cazorla too.
And while they are effective on the counter and on transitions, I've seen poor teams push them back and make them look very one paced. Even Chelsea had about 60% possession against them at the Bridge, and Celtic got on top of them for long spells too. Dunno, don't think they are that much bett than us. Individually they have more class, but I'd strongly fancy us to take them at The Emirates. Think they'd struggle with a higher tempo and higher energy game.
