Chelsea fans have been accused of failing to create an intimidating atmosphere at Stamford Bridge - by a Marseille defender who used to play for Charlton.
Defender Souleymane Diawara moved to The Valley in 2006.
He said: "Stamford Bridge is nothing like Marseille, it didn't impress me at all.
"I'm lucky enough to have played there twice but it is quiet there. I think the Chelsea fans will be more impressed when they come to the Velodrome."
