Pochettino is crystal clear on Pardew's Palace

Spurs beat their London rivals 5-3 on New Year's Day for a first victory over the Blues since 2010.

It followed a spate of poor results against the Premier League's top teams and moved Pochettino's side above Arsenal in the table and into fifth place, just two points off a place in the top four. Another derby this evening sees Tottenham travel to Palace to take on the Eagles, who are under the leadership of new boss Alan Pardew, and Pochettino feels his squad must now have the feeling they can beat anyone and everyone in the league. "We are capable of showing what we showed in that game," the Argentinian said.

"Why not keep that level in all games? We know it is not easy but if we are capable of that performance against Chelsea we need to keep those performances in the future.

"It was important to stop this idea (of not being able to beat top sides) The players now feel that it is possible to beat the sides like Chelsea.

"We are very happy, the 5-3 against Chelsea means more than just one victory. It is a belief in our skill and in our mentality, but now we need to show again against Crystal Palace the same mentality to show we are strong - if not there is no good thing."

Both Pardew and Palace have frustrated Tottenham earlier in the season. Newcastle won 2-1 at White Hart Lane when still under the guidance of the new Palace boss, while Neil Warnock led the Eagles to a goalless draw in north London at the start of December.

The short trip to face struggling Palace would not normally be treated with the same level of trepidation as a game against league leaders Chelsea.

But, with firm fan favourite Pardew now in charge of Palace, Pochettino knows it will be a tough test.

"We analysed Palace, it was a few weeks ago - now they have a new manager who may have a new team and a new way of playing," Pochettino added.

"It is more difficult. He (Pardew) did a great job at Newcastle."
