The 40-year-old believes the Gunners could be in trouble if Olivier Giroud picks up an injury, with few alternatives to the French striker available to Arsene Wenger
Parlour, who made over 400 appearances for Arsenal in all competitions, joined the list of pundits praising the club for signing Real Madrid star Mesut Ozil on transfer deadline day.

"I'm worried about the forward line," Parlour told The Daily Star. "Giroud was excellent against Spurs.
"But if he does get a niggle or gets injured, then the next player that can play there is Theo Walcott because Lukas Podolski is out injured.
"It's the only position I am worried about. If Giroud does get hurt, they are going to be light.
"They got Ozil in – great. But could they have signed a striker as well?"
Giroud has started the 2013-14 season in excellent form, scoring in all three Premier League matches Arsenal have played.
After an opening-day loss to Aston Villa, Arsenal rebounded with wins over Fulham and rivals Tottenham as they climbed to fourth in the table.
