Barcelona are reportedly very close to agreeing a deal for Gremio midfielder Arthur, and the club are also said to be open to allowing left-back Lucas Digne to leave in the summer.
Ernesto Valverde's side have made a €30 million offer for Arthur, although the Brazilian side are said to want €36 million, per Sport's Joaquim Piera.
Arthur has a €50 million release clause in his contract, but Gremio are willing to negotiate as the midfielder is keen on a move to Camp Nou.
However, the Brazilian will not move to Barcelona until after the FIFA 2018 World Cup at the earliest, and Gremio want him to remain at the club until December.
