De Ligt is a transfer target for a number of clubs across Europe including Man United and Liverpool.
Jamie Carragher heaped praise on Matthijs de Ligt, labelling the Premier League transfer target as "a leader" and a "top class" defender.
The Holland international is a transfer target for a number of clubs across Europe including Manchester United, Juventus, Barcelona and Liverpool following a brilliant display for Ajax in the 2018-19 season.
However, former Liverpool great Carragher hailed the 19-year-old’s skillset after he captained Ajax to the semi-final of the Champions League this season.
"It's unbelievable what De Ligt is doing at 19-years-old. The performances we saw him give in the Champions League were outstanding,” Carragher told Sky Sports.
"But it's not just his ability – there's obviously been a lot of great young defenders, teenagers we've seen over the years with talent – but also his leadership qualities.
"I saw him giving a speech at the end of the season on a stage, speaking like he was 29, not 19. To be captain of Ajax and with them getting to where they got to this season, he's clearly a leader and top class."
He added: "He's got the physical attributes too. I played that position as a young kid and sometimes you can make mistakes by getting knocked about if someone is too strong for you or too quick for you because you're not fully developed physically.
"But that's not a problem for De Ligt at all, he's a man. He looks like he's 24 or 25. That's a massive advantage for him at a young age.
"There's no guarantee with any player but you look at De Ligt and, for me, it's almost like a guarantee he's going to be a top player."
