Arsenal will be without the services of Mikel Arteta for this week's Champions League clash against AC Milan.
The Spanish midfielder will miss the tie after suffering concussion during his side's 2-1 win over Liverpool at the weekend.
Gunners manager Arsene Wenger also revealed that Yossi Benayoun and Abou Diaby will be absent at the Emirates Stadium.
"We have lost Benayoun, Diaby and Arteta as well," Wenger told reporters. "Arteta has to rest for a week. Rosicky is doubtful too. But we will put out the best side for us to qualify."
Arsenal will need to overturn a four-goal deficit if they are to qualify at the Italian's expense.
