Belgium kinda created this problem for themselves. Trossard and KDB have got in each others way all tournament and had them struggling to created space so their solution was to drop Onana and add another player who likes to play in the same area and leave Tielemans to be the 6.
I'm starting to think that a lot of the managers for the European teams are calling it in and relying almost entirely on a handful of big name players to save their asses.
