For winning the league on Sunday, Young Boys have secured a slot in the UEFA Champions League qualifying round.
Chaiwa and his team will now hope to qualify for the Champions League group stage for the fourth time in the club’s history.
Young Boys last competed in the Champions League in the 2021/22 season. They finished bottom in Group F, behind Manchester United, Atalanta, and Villareal.
Chaiwa could become the youngest Zambian to play in the Champions League if Young Boys go past the qualifying round.
He is also expected to make a cut in Chipolopolo coach Avram Grant’s squad for the AFCON qualifiers’ final round in June.
