Arsene Wenger was not too positive regarding the injury sustained by Aaron Ramsey on Tuesday night.
The Welsh midfielder suffered a hamstring strain early in the second half of Arsenal's 2-0 Champions League win over Bayern Munich at the Emirates Stadium.
It was yet another hamstring issue in a long line of soft tissue injuries for Ramsey and according to Wenger, the 24-year-old is set to be sidelined for a little while.
"He is alright but very down because he told me that his hamstring is quite a tough one. He is out," said Wenger.
Ramsey was sidelined on three separate occasions last season with the most recent being in February when he missed three weeks.
