Footballers teasing their hair into elaborate styles is no new thing – in fact, it's compulsory! But there is speculation there is an extra special reason behind Cristiano Ronaldo's new barnet.
The Real Madrid star, 29, sported a Z shaved into the side of his head during Portugal's 2-2 draw with the United States on Monday night.
And it's believed the fashion statement was a gesture to Spanish boy Erik Ortiz Cruz.
The one-year-old had successful brain surgery in March to treat his cortical dysplasia which causes up to 30 seizures a day and Ronaldo's engraving is thought to mirror the scars left on the boy's head.

Erik's family couldn't afford his medical bills but Ronaldo covered the cost of the treatment and donated signed kit and boots to raise more money.
It isn't the first time the former Manchester United striker has shown his generous side.
Earlier in the year Ronaldo celebrated his Ballon D'Or World Footballer of the Year award win with children suffering from leukaemia, keeping a promise made on Spanish radio last year.
Ronaldo met the children on radio Cope show Partido de la 12 last November and said if he won he would celebrate with them.
Following the celebrations he spoke to one of the children - who will have an operation this month - saying: "Don't worry I have not forgotten."
