Manchester United boss Louis van Gaal insists he can handle the white-hot atmosphere of a Liverpool clash.
Having helped Barcelona beat Real Madrid in his first El Clasico when managing in Spain, he's confident of coping with the pressure tomorrow.
"I have to beat Liverpool as a manager of Manchester United. It is like that, of course," he said.
"But Barcelona versus Real Madrid was in front of 102,000 fans. The Nou Camp was adapted to 102,000 and they were sitting there and I won my first game against Real 3-0 and I was very pleased."
