Osasuna coach Jagoba Arrasate has criticised the club's support for barracking Mason Greenwood on Sunday.
The on-loan Manchester United forward made his Getafe debut off the bench, helping them to victory.
During his appearance, Osasuna fans chanted 'Greenwood die', as he marked his first appearance since assault charges were dropped in February.
"The chants of 'f*** Osasuna' were very bad and the chants against Greenwood were very bad too," Arrasate said.
"He is a player who, in the end, the justice system had its say.
"He is a great player and in the end it will be very good for Getafe.
"But if we talk about chants, we should talk about all the chants, not just some."
