Spurs secured an excellent 1-0 win over Manchester City this evening, but saw Harry Kane suffer an injury in the second half

Mauricio Pochettino believes Tottenham Hotspur will take a lot of belief from their 1-0 victory over Manchester City in the Champions League quarter-final first leg tonight, but failed to allay fears over Harry Kane’s ankle injury.

Heung-min Son scored the only goal of the game at Spurs’ new stadium to hand them a famous win in Europe against Pep Guardiola’s quadruple-chasing team.

Tottenham captain Hugo Lloris was the initial hero - saving Sergio Aguero’s penalty in the 13th minute - before the South Korean struck past Ederson with 78 on the clock.

A negative on a tremendous night for the Lilywhites in front of a partisan crowd was the ankle injury suffered by Kane early into the second half and the prognosis does not look promising.

When asked if he was worried the England captain would miss the rest of the season, Pochettino replied: “Yes.

“The news on Harry Kane is, if you see the action, it is an action that maybe twists his ankle and maybe he damages the ligaments again.

“We need to check in the next few days and it is so painful, but what can we do now? It is impossible.

“Only we can look forward and try to hope it is not a big issue and try to recover as soon as possible, but it doesn’t look good.”

Spurs are set to be without Kane for the second leg at the Etihad next Wednesday, but they will travel to Manchester with spirits high following this outstanding result.

It was the type of victory which showed why Tottenham are often talked about as title contenders in the Premier League even if it often fails to materialise.

The challenge for Pochettino and this group of players now is to replicate displays like this on a regular basis.

He added: “I am happy with the performance and I am happy with how we approached the game.

“Of course the performance was very good and the challenge for the future is to give this type of level and show this level and be consistent.

“Still I am happy and still there is a lot of work to do and Manchester City are the favourite to win the Champions League and of course it will be so tough.

“In one week it will be a completely different game, but there is satisfaction to win the first leg and it gives us belief that we are going to be there and fight a lot. I think it is a good result for us.”
