The 32-year-old claims there are not many better players in the Premier League than the Frenchman at the moment.
Payet was once again at his best as he scored two goals and assisted one in the 5-1 FA Cup mauling of Blackburn Rovers on the weekend.
"Yeah, it's unbelievable what he does," said the West Ham centre-half.
"When he is on it like this, like we see in training, I haven't played with or against anyone better.
"He's a magic player and the West Ham fans are seeing the best of him.
"He's on fire. He's been tremendous. When he's in the mood to play like he is at the moment, there are not many better in the league.
"I know it is easy for me to say he's one of the best players in the league because I play with him, but I see him in training and I know him as a lad in the dressing room.
"He just doesn't bring what he does on the pitch, he's also a great lad to have around the place and the fans adore him for bringing that sort of football to the club."
