Arsenal manager Arsene Wenger has confirmed that Aaron Ramsey and Hector Bellerin will be fit for Saturday's showdown against Chelsea at Stamford Bridge.

The pair were not involved in the Gunners' Champions League opener against Dinamo Zagreb, which ended in a 2-1 defeat to Wenger's side in Croatia on Wednesday.

However, Wenger has claimed that both are available for tomorrow's encounter, while a decision regarding defender Per Mertesacker is yet to be made as he has only just returned from an illness.

"We have no injuries and we left Ramsey and Bellerin behind [for the Zagreb game]," Wenger told reporters at a press conference. "They integrate into the squad again. Mertesacker may still be a bit short, I have to decide that today."

The Frenchman also confirmed that Jack Wilshere will undergo surgery at some stage next week.
