Tottenham captain Heung-min Son has insisted that they remain on track to achieve success.

Spurs have now lost four Premier League games on the spin after a 4-2 defeat by Liverpool.

While Son knows they have to improve at the business end of seasons, he believes there is cause for optimism.

"It was much better than against Chelsea, we tried to play, especially in difficult places," said the South Korea and Spurs captain.

"Obviously they're a very strong side and I thought we competed very well, especially in the first half before we conceded. Obviously when you concede a goal you try to catch up and play more risky and it was a tough result.

"Look, in tough moments we have to stick together. It's a great opportunity for us to get tighter and stronger. The four fixtures have been really tough and because they've been combined in a month, it looks worse. But we'll fight until the end. But still, it was a tough, tough afternoon.

"When you think about the start of the season and we were playing well, everyone was full of joy and there was no pressure. But now is the time that everyone has to step up and stick to what we want to do.

"As I said before, this is the time and opportunity to get even stronger and come together. When things are going well, it's all easy. But in tough moments everyone has to get it together and help each other."
