Mind-boggling soccer decisions for $800, Alex:
The fan, identified by Ajax as a 19-year-old who had been drinking, approached Alkmaar’s Esteban Alvarado from behind, but the Costa Rican keeper saw the supporter in time and skilfully tripped him. Alvarado then kicked him twice where he lay before stewards dragged the intruder off the pitch.
The referee Bas Nijhuis responded to the incident by showing Esteban a red card for violent conduct, prompting an outraged Alkmaar coach Gertjan Verbeek to order his side to walk off in protest.
