Southampton boss Ralph Hasenhuttl feels it is 'nonsense' for players like Japan forward Takumi Minamino to be flying across the globe for international fixtures during a pandemic.
Minamino, on loan from Liverpool, is set to join up with several other Europe-based players for next week's friendly against South Korea in Yokohama.
Saints will also have several other members of the first-team squad heading away following Saturday's FA Cup quarter-final against Bournemouth.
Striker Che Adams has been handed a first call-up by Scotland for their World Cup qualifiers, with midfielder Stuart Armstrong again part of Steve Clarke's squad.
