The 28-year-old goalkeeper joined the Blues in a £22million deal from Rennes in the summer transfer window.
Mendy has conceded just ONE goal in his first seven appearances in a Chelsea shirt.
With Mendy in-between the sticks, Frank Lampard's side have kept five clean sheets in a row for the first time since 2010.
He has also become the first Chelsea goalkeeper to kick off his Premier League career with three shutouts since Petr Cech in 2004.
If Mendy keeps another clean sheet against Sheffield United on Saturday, which you can listen to LIVE on talkSPORT from 5.30pm, he will become just the fourth goalkeeper to not concede a goal in his first four league games after Alex Manninger, Pepe Reina and Anders Lindegaard.
Cech, Chelsea's technicol director, played an influential role in bringing Mendy to Stamford Bridge.
He said: "We had to make sure it was someone everyone agreed on, not just me. It had to be the club, and especially the manager, who had to be comfortable with the choice.
"We had a list of goalkeepers. We presented it all to Frank Lampard. We talked with the scouts. We shared information. We gave the pros and cons of each goalkeeper.

"In the end, my knowledge of Edouard for the past three years helped. I think he's a goalkeeper who can still improve, with his work, professionalism and desire to be better every day.
"I'm convinced he'll improve more, and these aren't the best performances you'll see from Edouard Mendy."
Edouard Mendy is already equalling clean sheet records in the early stages of his Chelsea career.
