Jack Wilshere has been ruled out of action for three months after having surgery on his ankle, Arsenal have confirmed. Most seasons, normally around February or March, Arsenal call on an underused genius to save their campaign. Step forward Tomas Rosicky. The 34-year-old Czech midfielder can be relied upon to be a star performer in the second half of the season as Arsenal chase a place in the top four or some silverware. Rosicky provides experience, a steady head in midfield and some much needed quality.
