Vidic was determined not to feel sorry for himself.
"When I come back I want to be at the same level I was before my injury. This is one of the things that drive me on," he said.
"I can't change what happened. I have to get on with it. Even when you have an injury, there are some benefits. I know the stuff I am doing now will help me not to have this again.
"Of course, I am not happy to be out. It is a big injury. A long injury. But I am 30. I still have a few years to play.
"I don't believe I will be on top form as soon as I come back but when people say I can't be the same this is a challenge for me."
