Arsenal midfielder Abou Diaby is set to miss around three weeks with a new injury problem.
The injury-prone Frenchman was forced off the pitch after 16 minutes of yesterday's 2-1 home loss to Chelsea and will now be sidelined until the second half of October according to manager Arsene Wenger.
"It is a thigh muscle strain. It is a minimum of three weeks," he said. 26-year old Diaby managed just four Premier League appearances last season because of ankle and hamstring problems following just 16 appearances the campaign prior.
