Netherlands coach Louis van Gaal said on Monday that he thinks Cody Gakpo will "evolve much further" after the youngster's two crucial goals at the World Cup.
The 23-year-old already has 13 goals and 17 assists for PSV Eindhoven in all competitions this season and has been heavily linked with a possible move to a top European club, most notably Manchester United.
The Oranje need only to avoid defeat against already-eliminated hosts Qatar today to be sure of a place in the knockout phase.
"I had more or less expected that he would evolve this way but I believe that he's going to evolve even further, much further, so I'm not surprised (by his performances) at all," Van Gaal told a pre-match press conference in Qatar.
"It's marvellous that he can do this on the world stage."
The winners of Group A will face the Group B runners-up in the last 16, while the second-placed team will take on the other group winners.
England are currently top of Group B, with Iran sitting in second place. The Dutch are level with Ecuador at the top of their standings and goal difference will decide the group winners if both teams win their games.
Van Gaal said he would not take any unnecessary risks with Memphis Depay. "We're not taking any risks with Memphis because to become world champions we need Memphis...It's all about what I see, Memphis has to deliver as well."
