Tottenham Hotspur defender Steven Caulker has demanded a response from his side when they face West Ham United tomorrow.

Spurs have endured a disappointing week, losing to local rivals Arsenal before failing to secure Europa League qualification with a draw against Lazio.

Caulker believes that Spurs will turn the corner against if they continue to work hard in training.

He told the club's official website: "It's important for us to get our form back in the league.

"We made a good start to it. We hit a bit of a dip in form but we're a good bunch of lads and we're working hard every day to put it right.

"There's no denying it's a massive game for us and we're confident we can get three points and put the season back on an upwards spiral."

Andre Villas-Boas's side trail West Ham by two points ahead of their clash at White Hart Lane on Sunday.
