Van Der Sar Wants To Remain Number One
"I don't really care who is behind me, I just want to keep the jersey," he told Sky Sports News.
"Ben Foster is a good goalkeeper, there is no question about that, but the same can be said of myself and Tomasz Kuszczak.
"We are all working hard to reach the highest level we can, but people tend to be focused on Ben because they relate it to the England situation.
"I must perform and make sure I'm fit and playing at the level everyone wants me to be at."
