It's true that Arsenal does need to push their current goalkeeper, Wojciech Szczesny, for fear of complacency, but bringing in Emiliano Viviano would be far too extreme of a move in order to accomplish such a goal.
While Arsenal put on quite the offensive display last season, they allowed far too many goals to be successful. Much of that had to do with their young netminder, who, for all intents and purposes, looked bored between the goal posts.
Such a lackadaisical approach helped lead to a third-place finish for the Gunners and a need to fill holes, but Viviano is not the answer to the club's needs.
Most importantly, Viviano is fresh off a knee ligament injury that kept him out of Euro 2012. So not only is the netminder coming off recovering from a bad knee injury that could linger, he also hasn't played in quite some time.
The Gunners could end up bringing in an inferior goalie to their current one, thus totally negating any hopes of pushing their youngster to better play. In the end, Arsenal could still have an uninspired goalie and an even worse backup.
Besides, pushing a young goalie isn't always the best thing. Such a competition could hurt Szczesny's development and further throw him into the realm of disappointment. Constantly looking over his shoulder could spell disaster for Szczesny.
In that case, Viviano could be Szczesny's replacement and the Gunners would be stuck with a subpar goalkeeper as opposed to an up-and-coming one with a bright future.
Arsenal's resources could be better spent elsewhere, as well. This is a team sorely lacking depth, and the Gunners are in desperate need of a player off the bench who can come in as a substitution and make an immediate impact late in matches.
The Gunners' potential signing of Viviano won't put this club over the top. Instead, it would add more uncertainty and turmoil to a club that doesn't need it.
