Olivier Giroud complained of a hamstring problem after the win over Bournemouth, says Arsene Wenger

Olivier Giroud is the "only worry" for Arsene Wenger, who eased concerns over injuries to Theo Walcott and Mathieu Debuchy.

Giroud was again on the bench as Arsenal beat Eddie Howe's Bournemouth 3-1 at the Emirates Stadium on Sunday, but is a concern for Wenger after complaining of a hamstring problem after his substitute appearance.

Walcott put the Gunners back in front after Bournemouth drew the game level at 1-1, and despite taking him off for Giroud in the 76th minute following a knock, Wenger insisted it is the French striker's fitness which is troubling him.

"Walcott was just a kick," said Wenger. "The only worry we have is Giroud.

"He looked to touch his hamstring. We have to see how deep the damage is. He told me on his first movement he felt a twinge."

Debuchy was making his first appearance for Arsenal in over a year, but managed just 15 minutes on his return to the Emirates Stadium before limping out to be replaced by Gabriel Paulista.

Wenger downplayed the player's own concerns regarding the hamstring problem though, urging patience before putting a date on his recovery.

"Debuchy thinks it is a severe one, but don't go too far yet. I have to speak to the medical people," Wenger said.

"We have to let it breathe. Usually he would have an MRI in a couple of days.

"Debuchy had many setbacks so I imagined something could happen to him when I picked the squad."
