Giroud was mainly used as a substitute by the Gunners last season and the arrival of Alexandre Lacazette at the club at the club for a club record £52 million is likely to further reduce his chances of regular first team action next season.
"There's not many players who have that kind of luck because he's 18 years of age and has a red carpet open for him".
The 26-year-old recently penned a five-year contract at the Emirates Stadium and is eager to get stuck-in at his new club.
'Obviously there will be more competition, even more than last year, but it's always nice for a striker to feel the pressure.
Jack Wilshere has been left behind but that is down to his continued recovery from a leg fracture, while Alexis Sanchez and Hector Bellerin have been given additional time off due to their international commitments over the summer.
Alexis Sanchez and Shkodran Mustafi have been excluded after competing for Chile and Germany respectively at the Confederations Cup.
After the two clashes here, the Arsenal squad will make their way to Shanghai to face German powerhouse Bayern Munich on July 19, before travelling to Beijing on July 22 where they will battle London rivals Chelsea.
"Lacazette will make his debut here, yes", Wenger said.
"We have top quality in our squad, and at the moment I focus on that". He is an important player for us.
Barcelona are considering alternative right-back options in case they cannot sign Arsenal full-back Hector Bellerin, reports Marca.
Lacazette has been one of the top goalscorers in France for the past few seasons, finishing with 27 (1.03 per 90 minutes), 21 (0.64), and 27 league goals (0.85) in his past three seasons, according to Squawka.com.
