Arsenal take on Napoli in their final Champions League Group F match on Wednesday night.
PER MERTESACKER v GONZALO HIGUAIN
Had things worked out differently in the summer transfer window, then Higuain, signed by Napoli from Real Madrid for £34million, could have been leading the Arsenal attack. The Argentina forward scored a brace in the recent win at Lazio and giant German defender Mertesacker will have to produce another consistent display alongside Laurent Koscielny to shackle the 26-year-old's threat.
MESUT OZIL v VALON BEHRAMI
Arsenal's club-record signing Ozil scored a superb first goal for his new club when the sides faced off at the Emirates Stadium on Matchday Two in October, but has struggled for consistency since. However, the £43million German playmaker remains the main conduit through the Gunners' potent midfield. With Slovakian Marek Hamsik still sidelined by a foot problem, former West Ham midfielder Behrami is likely to be charged with stopping Arsenal from getting into their stride, while linking with Swiss Blerim Dzemaili to get things going for the hosts.
OLIVIER GIROUD v RAUL ALBIOL
France forward Giroud has grown in stature this season, with 10 goals at the spearhead of the Arsenal attack. Spain defender Albiol will be out to nullify Giroud's physical presence with a shut-out for the Italians, who have not kept a clean sheet in eight matches.
