Arsenal title winner Paul Merson is convinced by the potential Fabio Vieira.
Merson has seen enough to know that Vieira is an 'exciting player'.
Merson told Sportskeeda when previewing the postponed clash with Everton: “Fabio Vieira came on against Manchester United and made a good impact, but Arsenal need to bounce back after their first defeat of the season last weekend.
"Vieira looks like an exciting player, but I just hope they play their best team and don't look to experiment for the sake of it."
