Samuel Armenteros has warned Heracles they will lose him for nothing next summer if they do not allow him to join Ajax.
The Swedish striker has one year remaining on his current deal with the Dutch side and is anxious to make the step up to UEFA Champions League football.
"I have had three wonderful years and have to thank Heracles for everything," said Armenteros.
"I am now 22-years-old and have two full seasons as a player. I would like to develop further.
"Ajax is a step up. They are the champions and play in the Champions League. We are all born as humans and just like everyone else I want to reach the top.
"Heracles probably know what they can ask for me. Next season I walk out the door for free."
While one 22-year-old targets a move to Ajax, another looks set to leave as Aras Ozbiliz holds talks with Russian side Kuban Krasnodor.
The Istanbul-born forward played 12 Eredivisie games for Ajax last season but they are willing to let him go for a fee believed to be in the region of €1million (£800,000).
