Manchester United must play to win at Tottenham on Sunday, says Antonio Valencia.

United are desperate to snap their winless run.

Valencia told manutd.com: "Absolutely, it's very important that we go all out to pick up the three points against Tottenham.

"We've played very well. In every game we've played, we've performed well and we've played good football. But now we need to better that by winning and I think picking up a victory on Sunday will certainly give us a lot of confidence as we move further into the season and hopefully help us pick up more points in the future."
