So far judging by statistics from last season, Viera had a good season getting 14 assists and scoring 6goals, there is a good chance of Viera joining this Arsenal side and a good move at that. I personally think he will do great as a substitute and backup for Martin Odegaard. Though the main priority now seems to strengthening thier attack and full backs but adding a player or two to the midfield isn't a bad idea too.
