Zewlakow looks for new club
Zewlakow had been tipped to leave Excelsior Mouscron during the summer to join the Dutch champions.
The 26-year-old stopper had agreed a pre-contract deal to link up with the Amsterdam giants.
However, Ajax were unable to raise the finances to push through the transfer and Mouscron are now aiming to offload the Pole to another club.
The Belgian outfit's chief executive Gino Gylain admitted they were still trying to sell Zewlakow, who made two appearances for Poland in the World Cup.
Gylain told planetfootball.com: "We have a World Cup defender in Zewlakow who had a pre-contract with Ajax but they cannot pay for him so we have to look for another club."
