The 33-year-old has played no part in the Gunners’ pre-season fixtures after sustaining the injury whilst playing for the Czech Republic in an Euro 2016 qualifier against Iceland at the end of the 2014-15 campaign and is now set for an extended spell on the sidelines.
His agent Pavel Paska revealed the news to the Czech media on Wednesday and gave a timescale as to when the player will be able to return to action:
“The recovery is expected to take four to eight weeks,” Paska said.
Rosicky’s career with the North London giants has been blighted with numerous injury problems as he was ruled out for the entire 2008-09 campaign with a tendon problem and last season found himself below the likes of Mesut Ozil, Santi Cazorla and Aaron Ramsey in the pecking for a starting place in the star-studded midfield at the Emirates Stadium.
