Arthur is being linked with Juve in a swap involving Miralem Pjanic.
“He [Arthur] isn't good enough to establish himself in Barca's team," he told Tuttosport.

“This should make him understand that no-one at the club considers him irreplaceable.
“If he stays, he'll be one of many. If he leaves, no tears will be shed."
