Arsenal striker Olivier Giroud looks set to start his first game of the season in Tuesday's Champions League Group A encounter against Ludogorets in Bulgaria. The Frenchman made his second consecutive appearance of the campaign following his return from injury in the 4-1 victory over Sunderland on Saturday where he scored two quickfire goals after coming on as a substitute for Alex Iwobi. Giroud is expected to lead the line for the Gunners while Alexis Sanchez, who has played at centre forward for most of the season, will likely revert to his favoured position on the left flank.
