Danny Purdy saved seven euro of his pocket money to get a style like that of his favourite player, a news agency reported on Wednesday.
Danny's mother Sarah has refused to send him to Brooklands Middle School in Bedfordshire after teachers threatened him with isolation.
"We genuinely didn't think a haircut like Danny's was breaking the rules. As long as children wear their school uniforms correctly and work hard at school, I really don't see what the problem is," added Sarah.
But head teacher Steven Harrington-Williams has defended the school's stance and said they had held an assembly on uniform policy prior to the cut.
