While Giroud waits on his scan results, Wenger has to plan for the Besiktas game without the France international, Mikel Arteta and suspended Aaron Ramsey. Arteta sustained a sprained ankle in the first leg of the Besiktas tie, but he is expected to be back for the Manchester City game on Sept 13. A successful passage into the group stages of the Champions League is likely to see Wenger attempt to sign a defensive midfielder, despite the good news on Arteta. Arsenal are understood to have been in talks with Sporting Lisbon over William Carvalho, with a bid lined up for this week. Sporting value Carvalho at around £28 million and are keen to secure players on loan from Arsenal as part of any deal.
