Tottenham boss Harry Redknapp admits they face a huge test this weekend against Manchester United.
Redknapp admits it will be a tough task to get a result on Sunday but hopes his side will raise their game.
"It's a massive game. They're a great side," he said.
"People raise their game against them. They're a top, top team, unbeaten this year, people say they're not playing well but they haven't lost a game yet so they can't be doing too bad."
