It was an unfortunate accident but an accident Arsenal will suffer more than most because of the style of football they play and the skillful quick footed players Wenger likes to utilise.
Fair enough, but my reasoning is that it happens because there are too many clumsy and ott tackles in England, I'm not talking about the Shawcross one, a good example is the treatment of Barton the other week, those types of tackles are very regular and that's the reason for the injuries, not because Arsenal play faster football, that should be encouraged, the rash tackles discouraged. But we'll agree to disagree because you say the English game should stay the same and that's fine, it is an attractive game to watch
Also Arsenal didn't lose to Chelsea/Man Utd because of power/size of players, I'd say it was lack of defensive nous and inability to track runners (laziness?). Most of the goals were simple counter attacks or down to somebody in the defence failing. I also think that saying the think this team lacks is height and power is also a misnoma, I don't thing this team is as successful as Vieira, Henry et al. is that they were better, simply put, that team is almost impossible to improve. Football does run in cycles and one day in the future it'll be Arsenal's turn to be at/near the top for a few seasons, then maybe Man City's/Man Utd's etc etc.
Barcelona proved that all the passion/aggression etc. is nonsense really, who's their enforcer? Iniesta? Xavi? Busquets? Arsenal just haven't found the right mix to win the title recently and haven't had squads nearly as good as Man Utd and Chelsea have, they need to concentrate on defending much more, not buy a tall player
