Champions League semi-finalists Tottenham are “living a dream”, says manager Mauricio Pochettino.
Spurs host Dutch league leaders Ajax – who have knocked out Real Madrid and Juventus – in the first leg of their tie on Tuesday (20:00 BST).
It is Tottenham’s first Champions League semi-final, though they reached the last four of the 1962 European Cup, losing to eventual winners Benfica.
“You need to set your dreams to infinity and beyond,” said Pochettino.
“When you achieve things it’s because you dream them. To be in the Champions League semi-final with Tottenham was a dream five years ago – but we’re living the dream.
“You know we must always dream for the moon if you want to get something in the sky.”
Tottenham picked up only one point from their first three group games – but then wins over PSV Eindhoven and Inter Milan, and an away draw at Barcelona, took them into the knockout stages.
They eliminated German side Borussia Dortmund in the last 16 and Premier League rivals Manchester City in a dramatic quarter-final.
“We have a spirit in the team that we can achieve anything and all is possible – that’s our strength,” added Argentine Pochettino.
“We have a great opportunity to be here playing the semi-final. It has not happened often.
“We must show respect for our opponents and Ajax fully deserve to be where they are. It’s going to be a very competitive game.”
Spurs will be without top goalscorer Harry Kane, who is out with an ankle ligament injury, and fellow forward Son Heung-min, who is suspended.
Midfielder Harry Winks has had groin surgery and is not expected to play again this season.
However, midfielder Moussa Sissoko is back in training after missing three games with a groin problem, while defender Jan Vertonghen is set to return after being rested for the 1-0 loss to West Ham in the Premier League on Saturday.
