Chelsea midfielder Frank Lampard says they cannot afford to slip in tomorrow night's Capital One Cup tie with Leeds United.

Before flying back from Japan, Lampard emphasised Chelsea's need to re-ignite their domestic season, starting with the Capital One Cup quarter-final tie at Leeds on Wednesday.

He said: "We have to pick it up for Leeds. We have to go there and stand up and get our form back at home.

"Win this and we're in the semi-final and with the possibility of a decent draw but we've got to win the games. It's tough to go to Elland Road. There's a rivalry. We're aware of it and we have to play with passion and do the physical side of things. They're going to be right at it. We can't expect to go up there and tap it around and get a result."
