Fears of violence between England and Wales fans in Tenerife has led police to plan a major security operation for Tuesday's World Cup game.
There has already been some trouble with video footage showing a brawl outside bars on the largest of Spain's Canary Islands on Friday evening, with people wearing England and Wales shirts involved.
UK police fear people prevented from travelling to Qatar for the World Cup may have been involved in the incident in Tenerife, but added they have yet to confirm this.
