Spurs were beaten 1-0 by the Dutch side in Thursday's (06.03.25) first leg of their Europa League last 16 tie and Son warned that the team will have to play much better in next week's second leg if they are to keep their hopes of winning the trophy alive.

Son told TNT Sports: "It's nowhere near where we should perform. It was very disappointing that we performed like this, including me. It's a big wake-up call because next week is the biggest game of the season.

"We didn't create anything in the first half, sloppiness, not performing the way we should.

"Everyone is very disappointed about the individual performance and the team performance.

"There are no excuses, we were not good enough. It's just 1-0, it's still not finished, and next week we have to be much better."

Spurs manager Ange Postecoglou was also critical of his side's performance and felt that his team had the wrong attitude on the pitch.

The Australian coach said: "It was nowhere near the level it needed to be.

"It wasn't great from us tonight, pretty much all facets of the game. We didn't really get to grips with any part of the game. We struggled to gain any momentum with the ball, we weren't as aggressive as we needed to be without the ball.

"I don't think it's a matter of effort or attitude. I don't think it is going out there and not trying, but, like I said, we didn't really come to grips and have the right mindset to tackle an away fixture in Europe.

"You are going to face some pressure when you play away from home in Europe and weather the storm and get to grips with it, but we never really did so that was a disappointment."
