According to Goal, Man United is the newest club who registered an interest in the 26-year-old while they want to strengthen their midfield this summer.
Highly regarded by Atalanta, a deal will not come cheap, with the Serie A Club that requires a reimbursement of € 60 million for its services.
United came close to giving a deal last summer, together with colleague Premier League side Arsenal, Chelsea and Newcastle, but Atalanta refused all the claims.
Juventus and Inter Milan both remain interested in the Brazilian, but the asking price is currently being seen as an important stumbling block.
