The North London club arrived in the capital yesterday, amid doubts over the fitness of their star striker.
It comes after the Spurs forward, 25, suffered an ankle ligament injury which put him out of action for the final seven weeks of the season.
However, the England captain has been included in Tottenham manager Mauricio Pochettino’s 23-man squad.
Full Tottenham squad:
Hugo Lloris; Kieran Trippier; Danny Rose; Toby Alderweireld; Jan Vertonghen; Davinson Sanchez; Heung-Min Son; Harry Winks; Harry Kane; Erik Lamela; Victor Wanyama; Michel Vorm; Eric Dier; Kyle Walker-Peters; Moussa Sissoko; Fernando Llorente; Dele Alli; Juan Foyth; Paulo Gazzaniga; Christian Eriksen; Serge Aurier; Lucas Moura; Ben Davies; Alfie Whiteman; George Marsh and Oliver Skipp.
Kane said he was ‘ready to go’ as he made a return to first-team training, although club legend and former England boss Glenn Hoddle has said he should ‘not start’.
He said: “I’m absolutely delighted that he’s fit, but I definitely wouldn’t start him.

“I think what a sight it would be for the Spurs fans and his team-mates if he’s there with half-an-hour to go and the game is hanging on an inch or is heading into extra-time.
“What a sight to see him come on with Lucas Moura and Heung-min Son if goals are needed and what a sight if they are hanging onto the game, because he can hold the ball up.”
Tottenham, who finished fourth in the Premier League campaign, are today training at Real Madrid’s Valdebebas complex.
Their final warm-up session will then take place at the venue for the final, Atletico Madrid’s Wanda Metropolitano stadium.
If Tottenham lift the trophy on Saturday it would mark their first victory in Spain, as their previous record stands at drawn three, lost three.
Victory over Liverpool would also see Spurs claim a first Champions League title, having previously won only the UEFA Cup Winner’s Cup and the UEFA Cup twice.
Meanwhile, Jurgen Klopp’s Liverpool are bidding for a sixth Champions League trophy, after his side were runners up to Real Madrid in Kiev 12 months ago.
Spaniard Rafael Benitez was the last to manage the Merseyside club to victory in the competition in 2005, as Liverpool came from 3-0 down to beat AC Milan on penalties in Istanbul.
