Cameroon manager Volker Finke has called his players' behaviour unacceptable and a disgrace after their 4-0 World Cup defeat to Croatia.

The Spurs defender Benoit Assou-Ekotto headbutted one of his team-mates, while Alex Song was sent off for elbowing Mario Mandzukic.

"Some players behaved very badly, and that's why we have conceded four goals," he told French magazine L'Equipe.

Cameroon, who were also involved in a pre-tournament bonus row, have lost both of their first two games at this summer's World Cup.
