​Chelsea manager Frank Lampard has listed four Tottenham players who could cause his side problems when they travel to north London on Sunday.

The Blues are just one point clear inside the top four ahead of kick-off and could drop out of the Champions League places if they suffer a fifth defeat in their last six games against José Mourinho's Tottenham.

Looking to avoid a third straight defeat in the Premier League, Lampard has pointed out that his Chelsea side have to be on their toes to keep Tottenham's four key attackers quiet this weekend.

"A lot of problems because they have good players," Lampard told Soccer Saturday (via HITC). "When you talk about the good players, you can particularity talk about Son [Heung-min], probably the best all-round number nine in the world in Harry Kane.

"Lucas Moura. A talent. And Dele Alli. What we are seeing with Dele Alli is that he's getting into those areas off Kane and beyond Kane that I think he was getting into two or three seasons ago."

Tottenham's front four have scored 14 goals since Mourinho's arrival last month, with the club winning five of their seven games across all competitions.

Spurs needed a last-minute winner from Jan Vertonghen to pick up all three points against Wolverhampton Wanderers last time out, where Mourinho's side couldn't even get to double figures for total shots at Molineux.

But chances should come more freely for Tottenham this weekend as Chelsea have faced 33 shots in the Premier League already this month.

While Lampard is aware that Chelsea will need to be at their best defensively to stand any chance of keeping a clean sheet, the Blues will also need to be ruthless at the other end of the pitch.

Tottenham have actually faced more shots than Chelsea (38) throughout December, even though they've only lost one match.
