Speaking after Willock’s exit in January, Arteta insisted he was a player he thought highly of.
“Joe is a young player with great ability who is progressing very well and we are happy with his continued development,” Arteta told the Arsenal website.
“At this moment in his career, Joe needs to be playing regularly. At Newcastle United, he is going to a very good club with a top quality manager and staff.
