Arsenal striker Olivier Giroud believes Paris Saint-Germain are the favourites for their Champions League clash at the Parc des Princes on Tuesday.
The two teams have been drawn alongside Basel and Ludogorets in Group A and will be looking to improve on their respective performances in the competition last season.
Having made it to the quarter-finals in each of the last four years, PSG are most likely to take top spot in the pool, according to Giroud.
After coming from behind to beat Southampton 2-1 in the Premier League with a last-gasp penalty from Santi Cazorla on Saturday, the striker thinks similar spirit will be required against the French champions.
