But Juve star Ronaldo wasted no time trying to get the defender to Turin after Portugal edged Netherlands 1-0 in the Nations League final on Sunday.
The Portuguese forward was seen talking to the defender following the match, which saw Portugal edge De Ligt and co. 1-0 behind a goal from Goncalo Guedes.
Asked if Ronaldo had questioned if he would be his team-mate at Juventus, De Ligt told NOS: "That could be true, yes.
"I didn't understand him at first. I was a little shocked, so I laughed, but I didn't say anything.
"Shortly after the game you are not at all concerned with it, you are disappointed you have lost and that is the only thing you are thinking about."

De Ligt, Ajax's captain, has made 117 senior appearances for the club and was recognized with the Golden Boy award in 2018.
