Aaron Ramsey just suffered a horrible injury to his ankle, much like what happened to Eduardo a couple of years ago. Paul Masefield though, said that while it was a bad tackle, there was no "malice" in it, and proceeded to blame Ramsey for being "too fast" What the fuck!
I have a theory, totally not based on experimental data, just general man-on-the-street observations. This is the third time our players got their leg broken after suffering a bad tackle in a game: Eduardo, Diaby, and now, Ramsey. Our list of injured players also seem to be overly long. It seems ridiculous to assume that Arsenal's reputedly excellent network of scouts to somehow miss all these players injury-proneness.
I've often heard it said that Arsenal don't like it when their opposition plays rough, and I believe that the saying has subconsciously (maybe), influenced referees and players. I believe that match officials are more lenient when fouls are committed against our players, and I believe that other teams know they can get away with more when playing Arsenal.
The end result of all this rough play: more wear and tear on our players. It may not show up immediately in dramatic fashion like the injuries to Eduardo, Diaby, and Ramsey but the stress builds up and results in "regular" and "mundane" injuries which we pass off as our players being injury-prone.
