West Ham boss Slaven Bilic says they must fansitedbusr out their hooligan element.
He has witnessed, he explains, far worse before – back home in his native Croatia, where he managed Hajduk Split, when he took charge of Lokomotiv Moscow in Russia and during his time in Turkey at Besiktas.
“I didn’t expect it here to be fair,” he said. “England was so far clear of it. It’s a worldwide problem.
“To be fair, it’s a great reaction from the media, it should be stopped from the beginning.
“You don’t want to say, ‘Yeah they have the same problems abroad, it’s worldwide’ and then it grows. On the other hand, it’s much less than anywhere else.
“We have those few countries who don’t have it: England, Germany. Even in France when Paris Saint-Germain are playing it’s like Mayday. You are one of the few oasis that is still very good.
“It should be zero tolerance, there’s no such thing as overreacting.”
