Watch: Ugly scenes as Legia Warsaw thugs attack police before heavy defeat against Real Madrid
Legia Warsaw fans have once again shamed themselves in Europe as trouble kicked off before their 5-1 hammering against Real Madrid at the Bernabeu.
The Polish champions, who narrowly beat Dundalk to qualify for the Champions League group stages, have already been charged for violence in the stands when they played Borussia Dortmund a couple of weeks ago.
And today in Spain, sections of their support attacked Spanish police with reports of two officers treated for injuries.
On the match itself, Real moved into a commanding position in Champions League Group F after cruising to a 5-1 victory.
Gareth Bale scored his first European goal since December 2014 to give the hosts the lead in the 16th minute with a curled left-foot drive and an own goal by Legia's Tomasz Jodlowiec, deflecting in Marcelo's shot, doubled their advantage.
Miroslav Radovic pulled one back for the Poles from the penalty spot but Marco Asensio made it 3-1 in the 37th minute with a low shot on his Champions League debut.
Substitute Lucas Vazquez volleyed home a cross in the 68th minute and former Juventus striker Alvaro Morata rounded off the win by converting a pass from Cristiano Ronaldo, who is still waiting for his 100th goal in UEFA competitions, in the 84th.
