Mido has accused Middlesbrough of trying to avoid paying him his "financial dues" but said he will not be forced out of the club.
Mido had been set to join Eredivisie giants Ajax, but the striker said they had been unable to agree a fee. De Telegraaf reported on Friday that Ajax have now secured another target, with Mounir El Hamdaoui joining from AZ Alkmaar for €5 million.
Mido says Boro are still desperately trying to offload him but, with a year remaining on his current contract, he will only move if he feels the move is right for him.
"Middlesbrough are doing their best to force me out because they don't want to give me my financial dues," he told FilGoal.com. "It's not the first time for them to do that. They have done it before with several players such as Mohamed Shawky, Gaizka Mendieta and Jimmy Hasselbaink, but I will not be like them. I will not give up my rights.
"I will not leave Middlesbrough until I find a suitable offer elsewhere. If I don't find that offer, I will stay until the end of my contract and gain my financial rights."
Mido was left out of Boro's pre-season tour of Ireland as he was told to stay back and work on his fitness.
"I was dropped from the training camp because the club claimed I was unfit," he said. "This is something that has not happened to any other player in the history of football.
"It is only natural that the players be not fully fit at the beginning of the pre-season training camp, during which they get physically prepared to play in the new campaign. Moreover, I did not have fitness problems. I played regularly with West Ham in the second half of last season, except the last two league games, and lost seven kilograms during the summer."
