The 19-year-old has had an outstanding season for Ajax.
There is no young player in the world more coveted than Mattijs de Ligt.
First-half goals from Matthijs de Ligt and Hakim Ziyech put the hosts 3-0 up on aggregate after their 1-0 first leg semifinal win in London and seemingly cruising into next month's showpiece in Madrid.
The Catalans have now received a major boost in the race to sign de Ligt, who has rejected Manchester United's advances despite the fact that he has a £250,000-a-week deal on his table.
And the main reason for him being so dismissive is because United are no longer the big sell they used to be.
Trippier probably shouldn't be marking De Ligt, it's a David vs Goliath mismatch in terms of physicality, but the right-back still took a lot of stick from Tottenham fans after the goal.
The player though, has embraced the role and led Ajax by example, with the Eredivisie club set to play for a place in the UEFA Champions League final on Wednesday.
