Finke to investigate Assou-Ekotto headbutt

Cameroon head coach Volker Finke has promised to investigate the reason behind fullback Benoit Assou-Ekotto's inexplicable behaviour during and following the Indomitable Lions’ 4-0 loss to Croatia on Wednesday.

The Tottenham Hotspur left-back, on-loan at QPR last season, completely lost his marbles in the closing stages of the Group A 2014 World Cup encounter.

With the West Africans trailing 4-0 in injury time and frustrations boiling over, Assou-Ekotto headbutted his team-mate Benjamin Moukandjo.

His anger continued following the final whistle in Manaus as Samuel Eto'o, who missed the game through injury, was forced to restrain him in the tunnel.

All in all it was a disastrous World Cup campaign for the West Africans, who almost missed the World Cup altogether because of a bonus dispute which led to them arriving in South America behind schedule.

Before the Cameroon players turned on each other, Alexandre Song got himself sent off for a furious elbow to the back on Mario Mandzukic in what proved to be an altogether embarrassing night for Finke's side, who will be back on home soil quicker than they hoped.
