Ajax's young stars crashed out of the Champions League semi-finals to Tottenham on Wednesday night after squandering a 3-0 lead on aggregate.Goals from Matthijs de Ligt and Hakim Ziyech had given the Dutch side a comfortable margin in the second leg, but a stunning hat-trick from Lucas Moura turned the tie around.Moura scored two goals in four minutes just before the hour mark to give Spurs hope before bagging a 96th-minute winner, securing a place in the final.Ajax have been phenomenal in the Champions League this season, but in the end their relative lack of experience showed.At 3-2 they needed to change their tactics. Tottenham were growing stronger, yet Ajax kept trying to play free-flowing football instead of reverting to the basics.

On a number of occasions Ajax players gave the ball away in dangerous positions when they ought to have cleared it up the other end of the pitch.

And they were punished for it, which saw former Chelsea and Manchester United manager Jose Mourinho give them a lesson in tactics after the game.

Mourinho was asked on beIN SPORTS if you sometimes need to change your philosophy, to which he replied: "For me, yes. The philosophy is what makes a team grow up in the direction every team grows up.

"You need that base, you need that philosophy, you need a style of play adapted to the qualities of the players. Ajax deserve all the credit for that and all the admiration of people like us who love football.

"But football is a sporting battle and in battles you need strategy. To win matches, especially special matches, you need sometimes to go against your philosophy to win the football match.

"I think Ajax in the second half needed to hide their weaknesses better, because everyone knows their weaknesses. They have to copy with that.

"We saw many examples in attacking situations. We had other situations where [Daley] Blind or De Ligt... the basic thing you do when you have an advantage is keep your balance all the time.

"The balance starts with keeping the defensive line in position. After that, a certain number of players always behind the ball.

"They stuck with their philosophy, they played this second half like they were playing Vitesse in the Dutch league. They played like it was the group phase or one more game in their league.

"Tottenham changed, they used direct football very well, they were lucky they had the Gods of football with them. They chased that luck."

Say what you want about Mourinho as a manager, but since being sacked by United and becoming a pundit he's given some great insight.
