The £3million rsenal move for Brazilian teenager Marquinhos is at risk of becoming a legal battle after it was claimed the player had already agreed to join Wolves this summer.
The Gunners have agreed a deal with Sao Paulo for the winger, who has also given the green light for a move to Emirates Stadium.
There could be problems though as, according to reports in Brazil, a legal battle could ensue as Wolves have already agreed a pre-contract with Marquinhos. Arsenal and Wolves declined to comment when contacted by standard sports.
Marquinhos is said to have signed a five-year contract with Sao Paulo in 2019, when he was 16, but FIFA rules only allow players of that age to sign three-year contracts.
That would make the winger a free agent this summer and explains why Wolves believe they could have a pre-contract deal at Palace. Sao Paulo, however, agreed to sell Marquinhos to Arsenal in the summer for £3m and such a situation could lead to legal issues for the youngster.
The Gunners had sought to swoop in on Marquinhos after identifying him as a talent for the future, as opposed to now.
He was expected to work with the first team in pre-season and possibly be part of the Americas tour, but he could be loaned out to help him develop and adapt to European football .
Arsenal continue to work on transfers for the new season and one player ready to go is defender Daniel Ballard.
The Northern Ireland international impressed last season on loan at Millwall and can leave permanently this summer. Millwall want to keep him but Burnley, Cardiff, Sheffield United, Stoke and QPR are also keen on the 22-year-old.
