According to the Argentinian newspaper La Nacion, authorities have classified the match at the highest risk level for potential trouble. The hotels of both teams are to be guarded by larger police deployments.

Players on both sides have already stressed that this is only a soccer match.

The 1982 Falklands war between Britain and Argentina and the South Americans' continued claim to sovereignty is seen as a flashpoint for fans while the 1986 Hand of God goal by Diego Maradona still rankles with England supporters.

In the second round in 1998, David Beckham was sent off after Diego Simeone made the most of a kick, but the England player got his revenge with the winner from the spot in a 2002 group game.
