Van der Sar: Man Utd breaking new ground against Arsenal
"This game is going to be something new because we have never played English opposition in a two-legged European game before," said Van der Sar.
"We are all excited about it but at the same time, the preparation and way we go about our job will be no different.
"For us it is just two games on the way to something big that we experienced last year.
"That night in Moscow was fantastic and we will do everything in our power to achieve that goal again."
