9) Olivier Giroud
Striker Olivier Giroud signed for the Gunners from Montpellier for a fee of around £12m in 2012 and has done enough in a red shirt to justify the outlay to the Ligue 1 club.
A target man with a fine touch and the ability to bring players into play, Giroud has occasionally been criticised for a lack of pace and incisiveness, but is a useful player to have in any squad.
