Serero is out of favour at the Dutch giants but has attracted interest from teams in Germany and France, according to a source close to the player.
"Serero is definitely leaving Ajax," says the source. "The club has failed to renew his contract and he is free to join any team next season.
"The boy is not coming to play in South Africa any time soon. A few teams have made contact in Europe. There is a team in France that has made a serious bid. He is not in a rush to make a decision."
