This is pretty bad luck for the lad, but it's nobody's fault. I get that you're pissed off with Arsenal most of the time but attributing every little thing to the club as some kind of error is a bit meh.
Didn't say the injury was the club's fault. It was an error to sign him to begin with. I said it at the time he was signed, and so it has proved. We wouldn't have even signed him if Giroud hadn't got injured the game before the window closed. He's just another name on a long list of bargain bin panic buys who didn't work out. He did get us 1 big goal at Old Trafford so wasn't a total flop but was never good enough to sort a position that's needed sorting for years. Sadly it's the other knee this time, so with both knees gone in consecutive seasons he could be pretty much done now.
