PSV Eindhoven coach Mark van Bommel admits it is do or die for both his side and Tottenham on Wednesday night.
Spurs travel to the Netherlands to take on the runaway Eredivisie leaders with both teams needing a win to keep their Champions League hopes alive.
Neither side have picked up a point so far in Group B following defeats to Inter Milan and Barcelona, so the clash at the Philips Stadion is a must-win for both.
“Winning means you are still in the group, but if you lose it’s almost over,” said Van Bommel.
“Spurs have a lot of quality players and weapons to win games, but we have that also.
“In my opinion Inter Milan, Barcelona and Tottenham are almost equal, there are no big differences.”
Spurs are facing a team who, on the domestic front at least, are probably the most in-form in Europe.
They are five points clear at the top of the Eredivisie having won all their nine matches so far with a goal difference of plus 33, having thumped Emmen 6-0 on Saturday.
Spurs are also enjoying their best start to a Premier League season despite their players’ supposed tiredness following the World Cup.
Harry Kane has still not hit his stride this term and looked jaded again during their 1-0 win at West Ham on Saturday.
“I think all the top teams in Europe have that problem, I don’t think Spurs are playing badly, they can play in several ways,” added Van Bommel.
“It’s difficult, they played a long road in the World Cup and have some injuries but I think they are doing well.
“Part of being a striker is if you don’t score you are concerned, but if the team is playing well the goals will come.
“They have a lot of quality, if you are such a quality player it is only a matter of time before you start scoring again.
“If we only concentrate on Harry Kane it will be difficult to have an eye on the others, they have quality players not only up front but in midfield and with Kieran Trippier providing the crosses.”
