And the 19-year-old, who was not born when Ajax last reached the last four, was left stunned by what he and his team-mates had achieved.
Sources close to Barcelona have reportedly told ESPN that the Spanish club have the situation "under Control", and that De Ligt is only interested in a move to the Nou Camp. "It's very hard to play against us and our philosophy".
"We have defeated Real and Juventus, two intended title candidates.We are very proud, the supporters are proud, the city is proud".
"This year we won two competitions out of four, which is good, it's 50%. I knew we could do it, but the fact that we did is unbelievable".
"I already talked with the president, I will remain at Juve next season and we are already planning the next campaign". In an interview before Christmas he revealed that scouting reports were provided for both the defender and his Ajax team-mate Frenkie de Jong who will play for Barcelona next season after signing a €75million deal in January. "We look forward to it".
La Repubblica lamented Juventus's continuing failed search for a third European crown; their last came in beating Ajax on penalties in the 1996 final. We are in the semi finals, we have a chance but we are not favourites.
The entire Ajax team starting 11 on Tuesday was assembled at a cost nearly half of that which Juventus paid out for their Portuguese star in the summer.
"In fact, we probably should have won by more".
They also qualified for the Champions League semifinals for first time since 1997 with De Ligt scoring the winning goal as they knocked out Juventus in Turin. Reaching the semis has earned Ajax an added €12m in prize money, with a further €19m potentially up for grabs if the team progresses further.

However, it wasn't the case last night as David let an easy shot from Lionel Messi get past him, which drew criticism.
