Posted by:Junaid Effendi Posted date: Thursday, August 13, 2015 /comment : 0 Arsenal manager Arsene Wenger continue to suffer with injury worries as the medical team confirmed that veteran midfielder Tomas Rosicky is expected to be out for more than two months. Rosicky who is one of the most senior player at Arsenal has undergone a surgery on his knee, according to Arsene Wenger. The 33-year-old midfielder has been out since the start of the summer. He picked up a knee injury while representing his country Czech Republic in the start of June. Rosicky was also linked with a move away from Emirates Stadium this summer, however he signed a one year contract extension and now would be watching the games on TV. His agent Pavel Paska also revealed that his client could be facing more than two months on the sidelines with a knee problem. It was expected that the midfielder would return in the next few weeks until the medical team found that the knee injury needs a surgery which will further delay his return. However, this would not be a loss to the Gunners as he is not a regular player for them. Meanwhile, another midfielder Jack Wilshere is on the sidelines along with striker Danny Welbeck who is also suffering from a knee injury. On the other hand, full-back Hector Bellerin has now returned and could be starting ahead of Mathieu Debuchy in the coming game against Crystal Palace on Sunday. The young Spaniard was out with a muscle injury which caused him to miss the opening game against West Ham. Columnist: Shah Arsalan Share !
