Arsenal take on Montpellier in their Champions League Group B clash at Emirates Stadium tomorrow.
Here, Press Association Sport takes a look at some of the key battles ahead.
Olivier Giroud v Mapou Yanga-Mbiwa
Former Montpellier striker Giroud is finally finding his feet with the Gunners following a £12million summer transfer, after five goals in his last five appearances. However, Montpellier captain Yanga-Mbiwa will be out to shackle his old team-mate as the French side aim to keep alive slim hopes of Europa League qualification.
Santi Cazorla v Jamel Saihi
Spain midfielder Cazorla has picked up his form again after making an early impression since his move from Malaga, scoring in the 5-2 win over Tottenham on Saturday. Tunisian Saihi will be hoping for a chance to impose his game and stop the Arsenal supply line.
Thomas Vermaelen v Souleymane Camara
New skipper Vermaelen had produced a couple of indifferent displays recently, but put some solid performances in after being switched out to left-back. Senegal forward Camara will be out to provide Montpellier's main goal threat and stretch the Arsenal backline.
