Belgium's new coach Mark van Bommel has selected a 24-man squad for the first four Nations League matches. The team includes experienced players such as Kevin De Bruyne and Romelu Lukaku, as well as newcomers like AZ goalkeeper Jari De Busser, who makes his debut in the national team. De Busser has had a strong start to the season with AZ, which has earned him a spot in the squad. Van Bommel has been in contact with players, including De Bruyne and Lukaku, and has spoken with them via Facetime. He has also visited some players, selecting Lukaku for his specific qualities. Thibaut Courtois is not available for the tournament, having chosen not to be available on his own request.
