Marquinhos has signed an initial four-year deal with Arsenal with the option to extend by a further year, according to a report.

Following Arsenal’s official announcement of a deal for Brazilian teenager Marquinhos, Charles Watts reports that the young winger is signing a four-year deal with an option for a further year.

Arsenal confirmed Marquinhos’ transfer from Sao Paulo on Monday, following a few weeks of speculation.

The Daily Mail recently reported that Marquinhos had signed a pre-contract agreement to join Wolves in the summer before Sao Paulo decided to offer him to Arsenal.

Arsenal quickly wrapped up a deal, but Wolves believe their agreement with Marquinhos is legally binding.

They reportedly took legal advice on the matter, with the Mail claiming they were considering action against Sao Paulo, Arsenal, and the player. The current status of that potential action is unclear.

That was the second complication in Marquinhos’ transfer.

When Marquinhos signed his first professional deal in 2019, he agreed a five-year deal with Sao Paulo.

That length of contract is allowed by the Brazilian Football Confederation, but FIFA do not recognise first professional contracts longer than three years.

So, according to FIFA, Marquinhos is out of contract this summer, and Sao Paulo were unable to convince him to extend.

As a result, the young winger is technically under contract according to his local federation, but that contract wouldn’t hold up if put to FIFA.

The simplest solution for Sao Paulo was to sell cheap.

Arsenal opted to pay a minimal fee to get the signing done and build a relationship with Sao Paulo. That fee is believed to be €3.5m (£3m).
