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.
I am actually very disappointed with this injury as I happen to agree with you that he was never going to come in and score 20/25 goal a season. A good player but not great. I said that at the time and of course was jumped on by almost everyone. Of course I did not want him to leave, but if he could get a regular game at Arsenal then I was OK. Unfortunately for him this did not happen. He is a terrific bloke and this will be a massive blow to him.
Some said he was a snip at $18 m but I think you paid too much.
Lets hope he comes back better than before.
