Arsenal striker Olivier Giroud believes the gunners are the underdogs ahead of their first UCL game against PSG.
Both clubs are expected to take the top two spots in the group after they were drawn alongside Basel and Ludogrets.
PSG were held to a 1-1 draw in their domestic league, with Arsenal winning 2-1. And Giroud feels his side will have to raise their game to have any chance in the French capital.
“We knew this victory over Southampton would require character even if everything was not easy. The Champions League is a different competition,” Giroud told Telefoot.
“Paris will regroup from their draw and are the favourites and leader of this group. It is up to us to put doubt into them.”
PSG opted not to sign a direct replacement for club record goalscorer Zlatan Ibrahimovic following the expiration of his contract at the end of June, with Edinson Cavani entrusted with the responsibility of leading the line in his stead.
The Uruguayan has scored one goal in his first three Ligue 1 appearances of the season, but Giroud knows better than to take his counterpart lightly.
“Ibrahimovic had a very good season and it is important to them that someone takes over,” he added.
“Cavani, if he is having a good night, can hurt us, especially with his shooting.”
