Clubs who do not play a part in helping to banish violent fan groups known as “ultras” from football may be fined, docked points or relegated, the president of Spain’s professional league (LFP) said yesterday.

The government, soccer authorities and clubs are seeking to crack down on the ultras after a Deportivo La Coruna fan was killed before a La Liga match last weekend in organised fighting near Atletico Madrid’s ground.

Atletico have cut ties with their main ultras group, the Frente Atletico, while Deportivo shut part of their stadium where a radical group known as Riazor Blues gather. Members of both groups were involved in Sunday’s violence, police said.

“We are going to compile an official list of all the ultras groups,” LFP president Javier Tebas said.

“Clubs that collaborate directly or indirectly with them will suffer economic sanctions and could be docked points or relegated,” he added.

“We are going to consolidate the strategy to eliminate ultras from our stadiums.”
