Paul Merson remains unconvinced by Arsenal as title contenders, citing Mikel Arteta's lack of "trust" in summer signing Fabio Vieira.
Portugal under-21 star Vieira joined from Porto in a deal worth up to £34m, becoming the Gunners' first signing of the summer. The youngster arrived with an injury, though, and has been unable to hold down a starting spot since returning to the fold.
The new recruit's lack of minutes has concerned Merson, who won the old First Division twice with the London club. Despite Arsenal sitting top of the pile, and despite the arrival of Mykhaylo Mudryk appearing to be drawing closer, the former England international has played down his old employers' prospects.
