Arsenal captain Cesc Fabregas is confident he will shake off a hamstring injury in time to face Chelsea in an eagerly awaited London derby on October 3.
Fabregas sustained the injury in a 1-1 draw against Sunderland at the weekend and it was initially thought that he could have been unavailable for up to three weeks.
However, the midfielder is now optimistic that he will be fit to lead his side out at Stamford Bridge in a game that will be a test of both teams' title credentials.
"The injury is not as bad as we first thought," Fabregas told Spanish radio station COPE. "There is no muscle rupture and I will be back perfect in about ten to 11 days.
"I am working with an osteopath in Paris and just working day to day. I think I will make the Chelsea game."
Fabregas is still expected to miss the home game against West Brom on Saturday and the Champions League trip to Partizan Belgrade the following Tuesday.
In his press conference on Thursday, Arsene Wenger said: "I hope that he will be ready for the Chelsea match and that he will be fine, but at the moment we don't know. It's too early."
