Tottenham boss Mauricio Pochettino was delighted with his players after a 1-0 win over Manchester City for the first-leg of their Champions League quarterfinal.

Heung-min Son's goal separates the two teams going to Manchester.

Spurs had survived the concession of an early penalty, awarded on a pitchside video review by the referee after Danny Rose was judged to have handled Raheem Sterling's shot. Sergio Aguero stepped up, but keeper Hugo Lloris saved.

Pochettino said, "It was an unbelievable game. It was so tough. But it is still Manchester City and there is a second leg. We are happy as we showed great quality. The performance was good but there's still 90 minutes to go.

"It was a really good game. We were all excited. It's a quarter-final of the Champions League. The penalty save I think gave the belief to us. I think there were many positive things. In the spirit we played today, everything possible.

On Harry Kane's injury, with fears his season is over, he added: "We need to check tomorrow but looks like it is the same ankle and similar injury. It is very sad and very disappointing. We are going to miss him - maybe for the rest of the season. It is a worry for us. We hope it is not a big issue. But there is not to much time to recover. He twisted his ankle so we will see how it reacts in a few hours.

"Fabian Delph was very disappointed but he didn't realise Harry's intention was not to tackle him. In the action, both were very strong. But both didn't have the intention to make damage to another. That was why Fabian was trying to talk to him. Both were fighting for the ball."
