Juventus, whose stock lost about €400 million (Dh1.66 billion) in market value at its low, went ahead in the the 28th minute, courtesy of 34-year-old, five-time Ballon d'Or victor Cristiano Ronaldo, but Ajax's youth prevailed, with goals from two academy players - 21-year-old Donny van de Beek and 19-year-old Matthijs de Ligt - to send the club into its first Champions League semi-final since 1997.
"We were not favourites, but with our philosophy we again exceeded our limits".
But goals from Donny van de Beek and Matthijs de Ligt ensured Ajax would pull off an impressive comeback and book their place in the semi-finals of the competition.
He has scored five goals this campaign, one against Manchester United and a hat-trick which rescued Juventus in the last-16 second leg against Atletico Madrid, before returning from injury to score against Ajax. We had big expectations, but the Champions League is a unusual competition.
Now, in 2019, he's arrived on the world stage and has helped Ajax reach the semi-finals of the Champions League at Real Madrid and Juventus' expense. We look forward to it, ' said Ten Hag, whose side face one of the English pair in the next round.
But Ronaldo latched onto a Miralem Pjanic corner with a downward header that left Onana with no chance. "I've never seen a bag of money score a goal". It's all square! Ajax have that away goal back as van de Beek takes a shot from distance in his stride and coolly fires into the bottom corner.
"It's unbelievable. We are so happy that we did it today and so proud of the team", De Ligt told ViaSportFotball.
United coach Ole Gunnar Solskjaer's greatest night as a player came at the Nou Camp, but after losing the first leg at Old Trafford 1-0, his team needed to become the first side to win a European game there in 31 matches in order to progress. Real Madrid simply couldn't cope with the fluidity, and now Juventus have fallen to their tactical prowess. "Now we have to reset everything and concentrate on Saturday to bring the Scudetto home".
