Midfielder Denilson wants to leave Arsenal, saying: "I've been here for five years and won nothing."
The 23-year-old Brazilian joined Arsenal in the summer of 2006 from Sao Paulo but in that time the Gunners have fallen short of silverware. Their last trophy was the 2005 FA Cup.
"I've simply been to see (manager) Arsene Wenger and told him how I felt - and he has agreed to let me go," Denilson told The Sun.
"This has been the worst season of my life and I am so upset, so frustrated. I am a winner and I came here to win trophies but I've been here for five years and won nothing.
"A footballer's career is over very quickly so it is time to move on.
"I know some people think I'm crazy. I need a fresh challenge and although I know I'm taking a big gamble I am ready to take that risk.
"I can't see myself returning in a Chelsea shirt, or Liverpool or Manchester City - and definitely not Tottenham. I think my future will be in Spain or Italy."
