Ajax looked to have reached the Champions League final after another dominant display against Tottenham Hotspur.

The Dutch champions brought a 1-0 lead home from north London after an impressive performance last Tuesday, and they simply carried on what they started at Tottenham's gleaming new stadium in the more familiar surroundings of the Johan Cruyff Arena.

Goals from Matthijs De Ligt and Hakim Ziyech left Spurs with a lot of work to do in the second half, but Lucas Moura hauled them back into the tie with a four-minute double salvo.

Andre Onana the Ajax goalkeeper was crucial in his side holding on, but in the final seconds of stoppage time it was Lucas again who popped up, beating Onana to complete the most incredible of comebacks.

But what did we learn? Here are five things.....

1. Kieran Trippier struggles

There are Spurs fans who, throughout this season, have questioned whether the Kieran Trippier we saw last summer at the World Cup was detained by the KGB and replaced by a clone of near-identical appearance but far inferior footballing ability.

On this night in Amsterdam, it was easy to see where those concerns had come from.

After a rough display against Ajax in London last week, Trippier was feeble in defence as the Dutch champions went 2-0 up before half-time.

The England full-back was pulled apart by the speed and movement of the hosts, and in attack he only began to contribute as Spurs' forwards got them back in the game.

2. De Ligt proves again to be a star

The consensus is that Matthijs De Ligt will join his friend and teammate Frenkie De Jong in Barcelona next season, with the Spanish club moving heaven and earth to secure his signing and reports leaking from Italy in recent days that Marc Overmars, Ajax's sporting director, had told his Juventus counterpart Fabio Paratici that the deal to take De Ligt to the Nou Camp was done.

Should that prove to be the case, Barca will have upgraded their calamitous central defence by bringing in one of the stars of this season's Champions League.
