Guernsey FA chairman Mark Le Tissier has accused Turkey's Uefa Regions Cup representatives Ankara of "biting and pinching" during his side's 3-0 defeat.
Three second-half goals put an end to the England representatives' campaign in a match which saw Guernsey goalkeeper Tom Le Tissier sent off.
He said: "They were very physical, we've got players with bite marks and pinch marks and they play acted.
"That's not the way any other team would want to win."
During the match, Guernsey forward Ben Coulter appeared to complain to the referee about a mark on his body after being bundled into touch by a Turkish defender.
After the match, the England representatives' doctor complained to Uefa of a bite to one of his players.
Guernsey coach Tony Vance added: "We came here to have a game of football and they've just played different rules.
"I'm not being a bad sport here but biting, pinching, that sort of thing, spiting, that's not in the game."
We've done extremely well to qualify for this competition and we've done extremely well out here. The preparation has been excellent

Le Tissier said: "Unfortunately the officiating throughout the whole competition was pretty poor. They are Fifa referees but their performance left a lot to be desired so that was very disappointing.
"We're very proud of the way the players have conducted themselves and the performances they have put in under extreme pressure, they didn't retaliate and I have to commend them for that."
Guernsey won the right to represent England in the preliminary round Croatia by beating the Liverpool County Premier League 5-2 in May to win the FA National League System Cup.
Having drawn their opening game, the Channel Islands side beat Gwent County from Wales 3-0 before losing to Ankara.
Le Tissier added: "We're full of praise for their efforts, their achievements throughout the whole last 18 months of this journey.
"We've done extremely well to qualify for this competition and we've done extremely well out here. The preparation has been excellent, the players' commitment and the way they have conducted themselves has been exemplary.
"The fans that came out here, we had nearly 100 fans out here, they've been absolutely fantastic. They've made so much noise and they've been a credit to Guernsey as have all the players."
