Liverpool boss Rafa Benitez refuses to write off Manchester United's title threat.

"When the gap is 20 points, then I will relax," he said. "But with just this small difference all I can say is we must keep going all the time and not think about what other teams are doing.

"We were aware before we played West Brom on Saturday that Manchester United had lost, but it was not something that we allowed to effect how we played.

"If you spend the whole time with a calculator considering what others are doing, it will drive you crazy. You must concentrate on what you are doing. United may be trailing us, but we are not looking at what they are doing, only ourselves."

Benitez, who welcomed back striker Fernando Torres after a hamstring injury, added. "Manchester United still have a game in hand and the ability to make up points in just two other games is not that difficult for them.

"But with just this small difference all I can say is we must keep going all the time and not think about what other teams are doing."
