Football fans warned before Coventry and Leicester game
Police have warned football fans to stay out of trouble ahead of Saturday's match between Coventry and Leicester.
About 20,000 people are expected at Coventry's Ricoh arena for the local derby, dubbed the M69 clash.
Insp Malcolm Prestwich, from West Midlands Police, said: "Our clear message to any potential troublemakers is that we will not hesitate to deal with you robustly."
Saturday's kick-off has been brought forward to 1230 BST.
In 2008, about 100 people were involved in what was thought to be a pre-arranged brawl ahead of the derby match.
Police arrested 11 people and recovered knives at the scene.
"West Midlands Police is very experienced in policing football, especially local derbies, and for Saturday's fixture there will be a visible police presence both inside and outside the Ricoh." said Insp Prestwich.
He added: "While we do not anticipate any specific problems this weekend, we are, of course, aware of local rivalries and of a minority hooligan element in football who try to spoil things for the majority of law-abiding people."
