He told the Sun: “This is the biggest game we’ve played in the last two years.
“They are the champions. But a lot of people saw us last Sunday when we went to Liverpool. We stamped our authority and, although we only got a point, people said we should have won.
“We know we can win the title. But to show people we can do that we have to beat United. If we do that people will say ‘these boys can do it’.
“This is a game full of big players. But we beat them twice last year because we wanted to win more than them.”
