Juventus have moved to block Arthur from departing this month on-loan.
The midfielder is being linked with Arsenal.
Juve are looking to recoup about £35million and could demand a clause triggering an obligation to buy if Arsenal finish in the top four.
Arthur, 25, has been on the fringes of Max Allegri’s team this season. He has made little impact since arriving from Barcelona in 2020 in a £72.5m deal.
He is open to a fresh start which he hopes can help him reclaim a place in the Brazil squad before the World Cup.
Sources close to the player are confident a deal can be struck. One said: “There’s a very large possibility. Arthur wants to play. He knows Arsenal can give him minutes because the team needs it.”
