Achille Emana was left frustrated after failing to get a move away from Segunda Liga Real Betis yesterday.
The Cameroon international saw the UK transfer deadline fall without a deal in-place with interested Premiership clubs Bolton Wanderers and Birmingham City.
Emana rapped: "Why do I stay while Ricardo Oliveira and Mark Gonzalez were allowed to leave?
"The Betis directors do not even want to speak to my agent on the phone. Stuttgart, Bolton and CSKA Moscow have offered nine million (euros) for me and they refuse?
"I am not a slave, I will not return after the game that I play with Cameroon."
