The Gunners' 2-0 loss at home to Schalke followed by a draw in Germany has left them in a slightly more complex position in the group than one would have imagined after winning their opening two matches.
Yet a win on Wednesday evening would still see the north London side in a decent position to qualify top of the group and William Hill price a home win at 1/3 (1.33).
Montpellier, who are rock bottom with a solitary point from their four games, are offered at 8/1 (9.00) with the draw available at 4/1 (5.00).

While they were disappointing at home to Schalke, the Gunners are generally extremely strong at the Emirates in Europe with this bet paying out on 10 occasions in the last three seasons.
Montpellier, meanwhile, are enduring a disastrous campaign both in Europe and domestically lying 14th in Ligue 1 and losing to Olympiakos in their last Champions League match.
With confidence low, and having kept just one clean sheet in their last 10 matches in all competitions, the signs do not look good for the French side at the Emirates.
For a value bet trying backing Olivier Giroud to open the scoring against his former club at 11/4 (3.75). After a slow start to life in north London, the in-form France international has four goals in his last three matches and will be keen to find the back of the net against his previous employers.
