"I'm really enjoying myself," he told the club's official website.
"From the beginning, from day one I had a very warm welcome into the club from everyone. [Before I joined] I knew the manager, I knew the English mentality.
"I knew before my first day how things would be and that, for me, was very important. It was very important for me to come here and play for the manager."
The 29-year-old reveals that he has developed a very strong relationship with Pardew.
"I followed him, even when I left Newcastle," he added. "Every time I was watching Newcastle and then I was watching Palace, because we create something, him and me.
"We have a very good relationship, it's very faithful. He can trust me, I can trust him and that's why I was fully following his team. When he came here I was watching more Palace and became a lot more interested in the team. That's when he called me [about a transfer] and I knew the team before he started talking about them!
"That was really, really important for me."
