Adrian is desperate to find a way out of West Ham in January after losing his first-team spot to Joe Hart.
In an interview with Radio Marca, West Ham goalkeeper Adrian said: “The coach is not giving me much ball this year, but the data is there. It only remains to fight.
“The possibility also to play for the national team when you are not playing also disappears.
“The market will be reopened and an agreement must be reached because I am not happy in this situation.
“Try other leagues? I would not mind. I want to enjoy every Sunday and that is achieved by playing.”
Crystal Palace and Newcastle both expressed an interest in Adrian during the summer transfer window and the former could return in January having failed to recruit a replacement for Steve Mandanda.
