Van der Kraan believes the Liverpool defender could be more useful than Wout Weghorst in certain pressure situations, particularly when the Netherlands resort to crosses and direct play.
The idea is not to turn Van Dijk into a conventional striker. Instead, he would operate as a second forward, using his height, strength and timing at set pieces. His leadership could also help organise the team during a frantic final spell.
It would be a dramatic tactical switch, but one that fits the demands of knockout football. A defender stepping into the attack can unsettle opponents who are already defending deep.
The report says Brian Brobbey and Weghorst remain the more natural alternatives to Depay. Weghorst is familiar with the role of late-game target man, while Brobbey offers power and running in behind.
However, the Netherlands are reportedly dealing with wider selection problems. Xavi Simons, Matthijs de Ligt and Jurriën Timber are said to be unavailable, while Joey Veerman was left out of the final squad.
Van der Kraan says Koeman has focused on building “the best team”, rather than simply selecting the most individually talented players. That approach places even greater importance on tactical flexibility.
The report suggests Micky van de Ven could provide defensive cover in one-on-one situations, allowing Van Dijk to push higher when the Netherlands are chasing the game.
Whether Koeman would actually use his captain up front against Japan remains uncertain. But the opening fixture may reveal whether this is merely an emergency idea or part of a broader plan for surviving difficult moments in the tournament.
