Ajax midfielder Frenkie de Jong can see Mattijs de Ligt soon leaving.

The defender is a target for Barcelona, Juventus and Manchester City ahead of the January market.

"I think he will eventually leave for €68m," De Jong told Voetbal International before being asked about his own situation amid talk of leaving for Barcelona.

De Jong confessed he still studies the game of Barca captain Leo Messi.

"Because I think that's a nice player. I like to watch him. It is not to match him, that is not possible. When I look at a player to really learn, I often look up Xavi or Andrés Iniesta. Messi, of course, but that is different.

"I used to watch all Barcelona matches when they played with the three of them."
