Alli's continued development will no doubt be exciting to watch and if he continues to progress at such a quick rate for Tottenham then it is only good news for England fans too, as he is also a key part of Gareth Southgate's Three Lions squad.
"Maybe we can qualify, but in the end it will be hard when the opponent will be tougher than the one we played here", said manager Mauricio Pochettino.
PSV's opening goal also came from a mistake by Toby Alderweireld but Pochettino laid the blame at himself and his side's failure to take their chances rather than individual errors. We'll see what happens now in the game between Barcelona and Inter Milan but with only one point after three games, it will be so hard.
"We had control, but the most important thing is to score more than your opponent". He lamented their lack of clinical edge in front of goal and how they took their foot off the pace in the closing stages, suddenly slowing the tempo and losing their aggression up front. "We completely dominated and we had the chances to kill the game".
"In football you can not allow your opponent the time to be alive. In my opinion I think no, but we can not blame the referee". You can always make a mistake. "Why should Hugo apologise? No". Win this must-win match, he had said before the game, to prove you have what it takes to win the big titles.
"It's hard to judge the game", he said.
Pochettino, whose side are fifth just two points off the top two Manchester City and Liverpool, said he hoped the pitch would bear up given that on Sunday there is an National Football League match between the Philadelphia Eagles and Jacksonville Jaguars. In football sometimes that type of action can happen.
"Now we need to win three games that we have to play and some results that help us to achieve a place for qualification - but it's hard".
The midfielder Christian Eriksen added.
"Today the circumstances were against us but, again, we're not going to blame (anyone)".
Spurs boss Mauricio Pochettino: "If we need to blame someone it's ourselves because with all the situations and the circumstances in the game you must win because I think we were much better than them".
