Juventus are expected to make a decision on whether Arthur can leave on loan after Wednesday night’s Supercoppa final against Inter Milan.
Arthur is thought to be one of a number of midfielders Arsenal are looking at this month.
Manager Mikel Arteta admitted last week Arsenal want to strengthen in midfield. The Brazilian is also understood to be willing to make the move to the Emirates.

Juve boss Max Allegri is said to be unsure about letting him go, however.
The club want to move some players out to fund other signings. They have a number of central midfield players including Aaron Ramsey, Adrien Rabiot, Rodrigo Bentancur and Manuel Locatelli.
Arthur has made only seven Serie A appearances this season but played four out of six Champions League group games.

Arsenal will also consider offers for defenders Pablo Mari and Calum Chambers in this January transfer window.
