Wales international Chris Gunter has claimed that Panama will try to cause an upset against England in their group-stage fixture this weekend.
The two countries will clash in Group G this Sunday, with three points separating the two teams in the table.
Gunter played against Panama in a 1-1 draw with Wales last year, and he believes that the South American country will be desperate for a result against the Three Lions.
"I think we've seen a lot of games so far in this World Cup where teams are not scared to break up play and try to do everything they can to upset the bigger nations," Gunter told Sky Sports News.
"Certainly against us they were very physical and didn't really worry too much about the safer side of the game - if you want to put it politely! But I think England will know that. They had a very good start and if they can get a result it will put them in a fantastic position.
"They've got some good players and it will be a tough and physical game where they'll try and upset England as much as possible."
