has aimed a dig at Argentina after he was overlooked for a late call-up to their squad.
With less than a week until their World Cup campaign begins, Argentina have been forced to make two changes to their squad following injuries to Joaquin Correa and Nicolas Gonzalez.
Garnacho was tipped by many to secure a last-minute call-up with Argentina following his impressive performances for in recent weeks.
But the 18-year-old has missed out on a place in Qatar as Argentina head coach Lionel Scaloni opted to replace Gonzalez with winger Angel Correa, while Joaquin Correa has been replaced by Atlanta United midfielder Thiago Almada, who was named 2022 MLS Newcomer of the Year last month.
The decision does not appear to have gone down well with Garnacho, who liked a post on Twitter from a user who suggested he was overlooked because he is Spanish.
Garnacho was born in Madrid and is eligible to play for both Spain and Argentina. The winger has represented both nations at youth level but is still waiting for his first senior cap.
The closest Garnacho has come to his first senior international cap was with Argentina in March as he was called up for their World Cup qualifiers against Venezuela and Ecuador, however, he did not make an appearance.
Garnacho still has the opportunity to switch allegiances and could now opt to play for Spain after being snubbed by Argentina.
