Roy Hodgson has called for England supporters to be careful after three fans were attacked in Ukraine on Sunday.
England faithful arrived in Kiev a few days before the World Cup qualifier with the Ukrainians on Tuesday night but a trio were injured in an attack outside a bar in the city centre.
Hodgson said there was no room for football for this type of behaviour and urged Three Lions fans to keep their wits about them.
"We deplore it and everyone deplores it. I'm certain that the people in Kiev deplore that. I hope our fans are not so badly injured that they cannot attend the game," he said.
Superintendent Rachel Barber, of South Yorkshire Police, added: "We would urge supporters to enjoy themselves but to do so without upsetting anybody. I am pleased to say the atmosphere in the town is good, so in that sense what happened was out of the blue."
