Help! Struggling Ronaldo unveils new Mohawk hairstyle

Cristiano Ronaldo's World Cup is going from bad to worse and the Portugal star appears to have taken his frustration out on his famous locks, unveiling a new mohawk hairstyle during training on Tuesday.

While his arch rival Lionel Messi took his tally for the tournament to four goals with a sublime double against Nigeria, the Real Madrid man is still waiting to open his account as the Seleccao face a group stage exit. And an out of sorts Ronaldo, who has been struggling with a knee injury, perhaps in an ode to fellow former Manchester United No.7 and style icon David Beckham, shocked onlookers when he turned up at training on Wednesday sporting a mohawk.

Last year s Ballon d'Or winner and his team-mates face Ghana in a must-win game on Thursday night, but must also rely on Germany beating USA in Recife to reach the last-16 stage.
