Harry Kane's outrageous stoppage-time strike from the halfway line got Tottenham's pre-season off to a memorable start as Cristiano Ronaldo and Juventus were upstaged in Singapore.

Fans were left rubbing their eyes in disbelief as an entertaining International Champions Cup encounter at Singapore's National Stadium came to a stunning conclusion.

Sunday's friendly was heading for penalties until Kane's moment of inspiration in the 93rd minute.

Erik Lamela opened the scoring on the half-hour mark after Gianluigi Buffon parried 17-year-old Troy Parrott's effort.

Juventus returned from the half-time break strongly and levelled through former Chelsea striker Gonzalo Higuain, before star man Cristiano Ronaldo fired his side ahead.

Lucas came off the bench to level with a smart effort and set up a grandstand finish, with his goal provided by another substitute.

Tanguy Ndombele quickly made an impression upon coming on for his first Spurs appearance as the club-record signing superbly played through the Brazilian.

"Ndombele is a player that has the capacity to do what he did today," Pochettino said.

"But still it's too far away in his adaptation. It's only one week with us.

"Today he played more than I expected because our plan was to play him for only 15 minutes, but with the tempo in the second half it was good to give him 30 minutes.

"We are happy with him but still we don't expect too much. We know his talent and what he can add to the team but it's step by step and I don't want to put too much pressure on him."

Juventus counterpart Maurizio Sarri was not too downhearted after defeat in his first match as head coach.

"It was a difficult match today," the former Chelsea manager said.

"The preparation for this match has been difficult.

"Tottenham were quicker and more rapid, but this is natural because they are two weeks closer to the start of the season so they're in a more ready position."
