The next three slides may be contentious, particularly for those whose delicate sensibilities won't allow even the hint of criticism towards Wilshere.
However, there is a good chance that Arsenal may play quicker in his absence. That's because Wilshere hasn't yet mastered the subtle and sudden delivery that Cesc Fabregas and, to a lesser extent, Santi Cazorla can manage.
It's part of Wilshere's personality as a player to be neat and tidy in possession. Sadly, this can often lead to him taking the simple, short pass, when something different is needed.
This can often make Arsenal easy to defend, as too much of their passing is played in front of a defense, not aimed for in behind it. This author particularly remembers being at the Britannia Stadium when Arsenal were beaten 3-1 by Stoke City in May, 2011.
Wilshere and Aaron Ramsey were the midfield two that day. They both persisted in slowly working the ball from side to side and Stoke stayed comfortable. You know it's bad when Stoke fans chant "boring."
Of course, whether Arsenal plays quicker in Wilshere's absence could largely be determined by who replaces him. One man who could play a key role in some form is Tomas Rosicky.
Moving the ball quickly and always going forward defines Rosicky's game. The aging playmaker has impressed in brief cameos lately, and it would be a bold move from Wenger to start him.
However, Wilshere's replacement perhaps won't be as important to the pace of Arsenal's game,as the balance of the team.
