Gremio president Romildo Bolzan denied rumours of a €40 million agreement between the clubs, but the midfielder has insisted the transfer is on course
Arthur has indicated his move from Gremio to Barcelona is "on track", although the Brazilian club have denied a transfer is imminent.
Gremio president Romildo Bolzan suggested this week reports of a €40 million agreement are untrue, with the move not a "foregone conclusion".
Arthur was photographed wearing the Catalan club's jersey in a meeting with their sporting director Robert Fernandez in December.
Barcelona have tracked the midfielder since he shone in Gremio's Copa Libertadores triumph and Arthur believes his switch to the La Liga leaders is close.
