Arsenal have been handed a fitness boost ahead of their clash with Manchester City after Mesut Ozil returned to first-team training.
He was withdrawn in the final minutes of the 1-1 draw with Leicester City 10 days ago with an ankle problem and subsequently missed Germany's European Championship qualifying victory over Scotland on Sunday 7 September.
His absence from his country's win in Dortmund immediately threw the 25-year-old's participation at the Emirates on Saturday into doubt but he looked to have overcome the knock during Wednesday's session.
In a further boost to manager Arsene Wenger's plans, Mikel Arteta is back to full fitness after recovering from his own ankle problem. The Gunners skipper suffered a knock in the first leg of the club's Champions League play-off first leg draw with Besiktas in August but is likely to be ready to lead his side out on Saturday 13 September.
Aaron Ramsey has also confirmed he hopes to feature against the Premier League champions after suffering an injury scare on international duty. The 23-year-old rolled his ankle on Andorra's heavily criticised artificial pitch in the latter stages of Wales' victory on Tuesday 9 September but is confident it is nothing serious.
"I'll be alright - the pitch was very hard, there's no give in it, so I rolled my ankle a bit," Ramsey said. "Hopefully it will be nothing and I'll be available for Saturday. These are the games you want to play in and I'm looking forward to it."
England quartet Jack Wilshere, Calum Chambers, Alex Oxlade-Chamberlain and Danny Welbeck are expected to return to training while Alexis Sanchez, who played for 86 minutes against Haiti on Tuesday, is expected later in the week.
After featuring in Colombia's 1-0 defeat to Brazil on Friday 5 September, David Ospina is also expected to feature in Arsenal's squad for the first time.
