It's been reported in French/Italian/Brazilian sports websites that the PSG striker rejected a Pokerstars deal worth $3/$4m euro. Reason being "he doesn't like Poker".
Below is the only english translation I could find, but a google search and google translator would also find other ones with more details:
"According to the French newspaper Le Parisien, an international soccer superstar and "Paris Saint-Germain" striker Zlatan Ibrahimovic has denied a multi-million euro advertising contract with PokerStars.
The publication notes that a tentative agreement on a contract has already been achieved and the parties had only to sign the relevant papers, but Ibrahimovic changed his mind at the last moment. According to rumors, the contract envisages an annual salary of 3-4 million. Its noteworthy, that Zlatan is receiving 15 million per year on his contract with PSG.
Currently, Team PokerStars roster includes such famous athletes like Rafael Nadal, Ronaldo, Fatima Moreira de Melo and others."
