Chelsea midfielder Frank Lampard admits the derby against Tottenham is a must-win game in the title race.
Carlo Ancelotti's team will test their nerves if they narrow the gap to three points with a win against Tottenham on Saturday. Manchester United are at Arsenal the following day.
"It's vital we win," said Lampard, scorer of the opening goal against the Hammers. "We have to beat Tottenham and hope Man United slip up. It's a massive, massive game against a good Tottenham side. Our reaction has been great in the past few weeks but it's come very late. Goal difference could be important but if we slip up against Tottenham, goals won't come into it.
"Fernando Torres can play his part. He can make an impact against Tottenham, he's that sort of player. Whether it's him, Didier Drogba or Nicolas Anelka up front, we can score goals.
"You need those boys when you are fighting to win a title. When the games are tense and tight you need your quality players to come through - and Torres is certainly one of those."
