Olympique Lyon coach Peter Bosz is delighted to be counting on Emerson Palmieri.
The Chelsea fullback has joined OL on a season-long loan with the option to buy.
Bosz was eager to see Emerson signed and said: "I'm glad he's here.
"He was at a club where you have to win every game and he has a mentality that not everyone has."
OL have coughed up an initial loan fee of €750,000.
