Tottenham have the belief in themselves to be Premier League champions, insisted manager Mauricio Pochettino after his side found the mental and physical resources to net another late victor to beat Newcastle 1-0 and leapfrog Manchester City into second place. We believe in ourselves.
"But we are close. and we will fight to the end to be as high as we can".
The Magpies, meanwhile, are unchanged from the side which beat Manchester City 2-1 on Tuesday.
Just when it looked like Spurs might register their first draw this season, Son fired an 83rd-minute shot from outside the area which somehow crept under goalkeeper Martin Dubravka to put them four points behind Liverpool who play on Monday. He is like this, he gives you everything and when he's exhausted he says: "I need to change" or [that he] needs to rest.
When quizzed as to whether he would be lending his support to bitter rivals, Arsenal, for their Sunday clash with Tottenham's title rivals, Manchester City, Pochettino said: "No, why?"
"Every single game is a different solution but it's very important to believe we can score in every single moment".
"Of course I wanted to strengthen the squad, but if we can not and we can not sign then I need to stick with the project of the club".
Both sides enter the game on the back of positive midweek results but both have shown a habit of trailing at half-time.
"We want to touch glory, what we want is touch glory, we aren't here for business or because we want to win money, we start our careers because we want to touch glory", the Argentine added.
"You can be a victor but if you don't have the tools to win, it's hard. That is a very good example for everyone to follow".
"We have to give credit to Son because the shot was a good one - and we hit the post in the second half, that was a big chance for us".
"That is my decision - that he is going to be involved in the first team from today [Friday], and he is going to be like another player involved".
