Holland coach Guus Hiddink admits he's been surprised by the talent of PSV Eindhoven winger Memphis Depay.
Depay penned new terms with PSV last month, but remains a target for Tottenham, Manchester United and Liverpool.
"Depay has the potential to become Netherlands' best player," Hiddink told NOS.
"I've noticed that he has even more potential than I first thought now that I'm working with him.
"He still has plenty of room for improvement. I first thought that it was hard to approach him, but I was wrong. He is incredibly interested and keen to learn.
"I can't say yet whether he will start against Czech Republic, but that's definitely an option."
