Ronald Koeman compared the work the 19-year-old does with that of captain Virgil van Dijk, as he feels the youngster can only get better.
19-year-old footballer Matthijs de Ligt is being wanted by the biggest European clubs.
His 2018-2019 season with Ajax was almost perfect, and he attracted many eyes who now want to sign him.
And Netherlands national team coach Ronald Koeman believes he will be a very successful player when he grows older.
“We are happy to have that kind of defender in the national team,” he said to Four Four Two.
“One is only 19 and needs to make a good decision for his future, but he will do that.”
Koeman is proud of having a great defensive line: “He’s progressing well. Of course, Virgil van Dijk is a bit more experienced a player, who won a first big title.”
“To become a star, you need to win big titles. Matthijs had a great season in the Champions League and he will choose whatever is best for his future.”
“His big quality is he’s only 19. It looks like sometimes that he has the experience of a player of 25″ he added.
“That was great, that they had success in the Champions League, in the highest level competing against big clubs.”
“That makes the development of young players. He’s a great professional, really clever. He’s doing extra training,” he continued.
“He can improve, of course, because he’s not at the end of his qualities. That’s normal for someone of 19.”
“He will be better in some years. Let’s hope he will choose a big, big club. He deserves that,” the manager concluded.
