Ledley King believes Dele Alli and manager Mauricio Pochettino have been the key two catalysts for Tottenham’s revival.

Spurs head into the London derby with Arsenal on Saturday chasing their first English top tier title since 1961.

Club legend King was eager to single out both Alli and Pochettino in the build up to the game, but began with praising the contribution of the 19-year-old midfielder in his debut Premier League campaign.

“He’s been unbelievable,” King told Talksport’s Drivetime on Friday. “To make the step up he has done in the Premier League, even on the international stage with England, speaks volumes about the player and his confidence.

“But also the manager of Tottenham, being able to let him go out and feel so confident and to be able to play the kind of stuff he is playing.

“He is a big player for us, hopefully he’s got a big performance in him and hopefully he can make the difference.”

Alli has scored seven league goals and supplied five assists in his first top-flight campaign since making the move from League One side MK Dons last summer.

The youngster has been rewarded for his superb performances with a regular place in the Spurs side and an England call-up.

Main man: Pochettino has been the catalyst behind Tottenham revival

Pochettino was appointed as coach in 2014 and has managed to transform Tottenham into a consistent force.

They missed the chance to go top of the table on Wednesday night when they fell to a 1-0 defeat to West Ham and Alli spent an hour of that game on the bench because of a slight knock.

The chance to get their charge back on track comes up against title and bitter rivals Arsenal and King believes his former side will never have a chance like this again.

“I really do believe we will win,” King said. “I’ve played in enough derbies to know form goes out of the window in these types of games.

“The time is now. The two teams up there now will feel there’s a big chance of winning the league this season.

“I do believe it will be harder in the coming seasons. So for both teams – use the opportunity.”
