Arsenal boss Arsene Wenger says defender Laurent Koscielny could be in the squad to face West Ham United this weekend.
With midfielder Tomas Rosicky and striker Yaya Sanogo already available for Friday's game against Queens Park Rangers, the Frenchman explained that all injured players will soon be back in the squad, including midfielder Aaron Ramsey.
"From Sunday I think everybody should be fit and available," Wenger said.
"We might have [Tomas] Rosicky back in the squad and [Yaya] Sanogo back in the squad. [Hector] Bellerin, I don’t know yet, but certainly Rosicky and Sanogo will be available.
"David Ospina is available as well [but Aaron Ramsey, Mikel Arteta and Mesut Ozil] are all out. The closest at the moment is [Laurent] Koscielny. I believe he’s a bit short for Friday, maybe has a chance for Sunday.
"He [Mikel Arteta] is progressing well. It should be very quick now. He will not play before January. [Aaron] Ramsey has a chance to be fit for Southampton."
Asked to give an update on England international Theo Walcott, Wenger said: "He [Theo Walcott] had only two days training with the team, I will see how he is this week. But fitness-wise he is not far.
"It is more that Theo has basically not played since January, so it has been a year. He has been missed because first of all he is a top-quality player, a team player and when he got injured he was in fantastic form. So of course he is a big miss for us.
"[But] I think [we will see the best of him]. Theo was born in 1989, 25 years old, and it is the best age for a player of his quality. He is as quick as he was, believe me. I see it in training."
