You've taken this way out of context. Who suggested he was a genius? I simply posted a video of the game where he came on against Watford, which, if you watched the game, you would have noticed he changed the game for us and actually made us look like a functional team. Does that make him a genius? No, of course not, but if ten Hag is to use him next season, then I believe that will be the way, which i what I initially posted.
He talks a about creating ''several 10's''. Bascially, having players playing between the lines and making off the ball runs to create that space for other players. That is what Van de Beek was extremely good at Ajax. Yes, to you it may be pointless, but actually, the reason we create few chances against teams that play with a low block is because we have selfish runners - players who only run if they know it will put them in a good position to score. What we need; however, are selfish runners and I believe that VdB has these attributes.
Time will tell as to whether VdB will go onto be a success, but he'll certainly be used in the 8 (mezzala) or 10 position next season under ten Hag.
