Sevilla, currently 17th in the Spanish top flight, lost 1-0 away at bottom side Real Oviedo on Sunday. Some supporters met the team at the airport to insult them, while others wearing masks gathered at the club's training ground.
The Spanish league issued a strong statement condemning the behavior, which comes as the club continues to struggle in the league. Sevilla faces ongoing challenges both on and off the pitch as they battle against relegation.
