According to Foster, Garnacho's focus on his appearance, particularly his hair, is a concern. Foster thinks that the 20-year-old Argentine player's priorities should be on working hard for the team and contributing to its success, rather than his personal grooming.

Foster has urged Manchester United to consider selling Garnacho this summer, as he thinks the player's attitude and behavior are not what the team needs. Instead, Foster would like to see Manchester United sign players who are good, honest, and hardworking, and who will put the team's interests first.

Foster compared Garnacho's behavior to that of Brennan Johnson, a player from a different team, who looked like he hadn't had a haircut in a while but still gave a great interview after the game. This contrast, according to Foster, highlights the difference between a player who is focused on the team and one who is more focused on himself.

Foster wants Manchester United to sign players who will work hard for the team and support their teammates, rather than those who are more concerned with their own appearances and attitudes.

Foster's comments about Garnacho and his attitude have sparked a debate about what qualities Manchester United should be looking for in its players.
