Arsenal are in talks with São Paulo over a deal for Brazilian winger Marquinhos.
The highly rated 19-year-old is keen to make the move and São Paulo want to strike a deal for risk of losing the teenager for free when his contract runs out.
Marquinhos signed a five year contract in 2019 but FIFA have refused to accept it as he was underage when he signed so the contract is only valid for three years under normal regulations.
Sao Paulo have tried to convince him to sign an extension but he has turned down their offer.
