Wolves and West Brom warn fans over behaviour after trouble at last derby

The clubs said they had worked "closely with the Safety Advisory Group, local authorities and police to ensure appropriate arrangements" were in place for Sunday's Championship game, which kicks off at 12:00 BST.

Fans were "reminded that anyone found engaging in violence, discriminatory behaviour, entering the pitch or trackside areas, throwing missiles, using pyrotechnics or breaching ground regulations risks arrest, prosecution, football banning orders and long-term or permanent exclusion from their club".

The two clubs asked supporters to only use tickets bought through official channels and to sit in the correct designated home or away area.

"Anyone found attempting to access, or being in an incorrect area, will be refused entry or ejected and may face further sanction," they added.

The clubs also asked fans to arrive in good time to allow for security searches and stadium entry procedures, follow instructions of stewards and police and report any unsafe, discriminatory or anti-social behaviour.

They said: "The overwhelming majority of Albion and Wolverhampton Wanderers supporters attend this fixture to support their team passionately and responsibly, and we are confident that will once again be the case."
