The 29-year-old also says that the Palace faithful have made him feel welcomed at the club since his move from Paris Saint-Germain in the summer.
"Of course [they helped], of course," he told the club's official website.
"The support and the atmosphere at Selhurst and away from home is incredible. They're so loud! The fans are amazing really.
"That made me happy [when I joined] and it keeps making me happy every day and every game we play. It's always good to have that kind of support and it gives me the confidence, the strength and the power to give everything for them."
