UEFA said they were viewing the trouble as being unrelated to the tournament but said that position would change if there was any crowd disturbances surrounding England’s games.

A UEFA spokesman told the Press Association: “From our perspective we view it as unrelated to the tournament. It is not being viewed as football hooliganism by UEFA.

“However, if it changes – and we hope it doesn’t – and there is trouble around a stadium or around an England match that position could change and we would have to review it.

“At the moment however we are viewing it as the sort of problems that might be encountered in any busy beach resort where people have been drinking too much. We are not relating it to the famous ’yellow card’ or saying that ’any more trouble and we will throw England out’. We are leaving it to the Portuguese authorities to deal with it.”

UEFA’s executive committee issued a final warning to England during the last European Championships in 2000 that if there was any more crowd trouble they would be expelled from the tournament.

However, so far football authorities have been very pleased with the crowd behaviour surrounding England’s match against France in Lisbon on Sunday.
