Brazil and Real Madrid star Vinicius Jr is 'trying to get out of his £7million-a-year deal with Nike after the sportswear giant gave him old boots last season'.
Vinicius, 22, who has been one of the shining lights for his country at the World Cup in Qatar, feels 'unfairly treated' by the company.
According to O Globo in Brazil: 'Vinicius has told his lawyers to attempt to get him out of his Nike deal.'
As it stands, he is still under contract and continues to wear Nike boots at the World Cup, where he scored the opener in his side's 4-1 win over South Korea on Monday evening.
Vinicius Jr's deal with the sportswear manufacturer runs until 2028 and the lawsuit was filed just before the World Cup.
He wore an old version of Nike Mercurial boots during Real Madrid's run to the Champions League title last season.
And the rapid attacker thinks Nike should give him more recognition as one of their biggest stars.
His performances for Real Madrid last season and this term have been outstanding and elevated him to another level.
And the former Flamengo player has deals with EA Sports, Vivo, Casas Bahia, BetNacional, OneFootball, JetEngage, Golden Concept and Royaltiz and Pepsi.
If Vinicius Jr does indeed manage to cut ties with Nike, there will no doubt be a scramble for his signature from competitors such as a Adidas, Puma and Reebok.
He will next be in action for the Selecao when they play Croatia on Friday in the World Cup quarter-final.
