Waddle, who won three titles in as many years for Marseilles, fears the club's fans will be in for a disappointment.
He told the Irish Independent: "I can't understand the connection, why they've looked at him. Unless someone's built him up into being Zinedine Zidane, I don't know how he got that move.
"He'll do well to get in the team. Normally when you strengthen your team you bring in a player who's different from what you have but Marseille have a lot of players like Joey. If they think he's going to make a difference by dribbling or scoring goals or making goals ... I don't think they'll see that. They'll see a player who passes it and plays simple football, and Marseilles fans, who like clever players, will wonder what the reason for signing him was. I think it is a strange move for both parties."
Waddle added: "So far he's played 70 minutes against Fenerbahce. They were losing 2-0, they took him off and drew 2-2. He'll do well to play football and if he's not playing, will Joey be happy? We'll probably find out on Twitter.
"It's a fantastic club with fanatical support -- if he upsets the supporters he might as well leave town. I wouldn't bet against him upsetting the supporters, but if he plays well, they'll take to him."
