Barcelona already have a deal for Arthur Melo to join in the winter, but they want to speed up the operation so that he can come during the summer, according to Roger Torelló in Mundo Deportivo.
Grêmio do not want to let him go early, and have at every turn, insisted Arthur will stay until the winter, which is the end of the Brazilian league season.
But Barcelona are said to be confident they can bring him earlier, in time for preseason, which starts on the 11th.
Last season, Yerry Mina was brought from the Brazilian league to Barcelona in the winter. The consensus says that this was not the best move, as it did not give Mina enough time to adapt to his new country and team.
Arthur himself is said to be eager to join Barça and start a new chapter in his career as soon as possible.
