It's the third home game in twelve days, but Sharples is backing the Gloucester public to be there in force once again for the team.
"The crowd is so important when they act as that 16th man, carrying you forward in the last couple of minutes when the scoreline is close.
"We all really appreciate the support and we know how much rugby means in this part of the world. It'll be a massive occasion, no doubt we'll have huge support and we'll be looking to do them proud."
Just over a year ago, Gloucester welcomed another big French side in Toulouse to Kingsholm and emerged triumphant. Sharples is hoping for a repetition of what was a superb evening.
"Toulouse was obviously a fantastic win for us, and the atmosphere on Friday night against Quins was reminiscent of that night.
"It was really rocking at Kingsholm and the crowd was fantastic and hopefully we'll be able to put in another big performance and make sure it's an occasion to remember."
