Wenger said: "I'm not very happy with the tackle. "We know what we are expecting, a battle everywhere, but we have now lost three players to horrendous tackles and I refuse to believe it's always coincidence. "I don't believe it when you are hit as many times as we are. "I just believe in what I see and when you see a player getting injured like that it's not acceptable. Commitment is right, but that is not right. "All the questions I get in press conferences about we don't fancy the physical side of it, that's the result." Welsh midfielder Ramsey, 19, was taken straight to hospital after players on both teams held their heads in anguish around his stricken body. Wenger added: "We know it's a bad injury. We have to transfer him to London tonight to see if he needs emergency surgery. "We don't know how long he will be out but it's certainly long term."
