Mauro Júnior recently received his first call-up to the Brazilian national team, with coach Carlo Ancelotti describing him as an interesting prospect due to his ability to play as a left-back. Bosz agrees that left-backs are scarce, and he believes the KNVB should have acted sooner to select Júnior. According to Bosz, the KNVB had the opportunity to select Júnior since 2022, given his long-term residency in the Netherlands. However, neither coach Ronald Koeman nor director Nigel de Jong took any action to approach Júnior about joining the Dutch national team. This missed opportunity has been highlighted by Bosz as a significant oversight by the KNVB.
