Brazilian midfielder Denilson has stunned Arsenal by announcing that he wishes to leave the club.
The 23-year-old has been on the Gunners' books since 2006 and has made over 150 appearances for the club.
He has, however, grown disillusioned with life at the Emirates and believes the time has come to move on.
The Samba star claims a lack of silverware is to blame for his transfer request, with Arsenal having gone six years since they last picked up a trophy.
Denilson feels he needs to make a fresh start if he is to make the most of his career and sees himself playing in the Primera Liga or Serie A in the near future.
"This has been the worst season of my life and I am so upset, so frustrated," he told The Sun.
"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 for me to move on.
"This is not a sudden decision. I made up my mind eight months ago.
"I was fed up of coming home and feeling down.
"But I haven't said anything until now because I did not want to disrupt the team during the season. And I haven't caused a big scene.
"I've simply been to see Arsene Wenger and told him how I felt and he's agreed to let me go.
"I know some people will think I am crazy. They are right. It is a great club with a great organisation, a great manager and so many talented players.
"Yes, I make a good living at Arsenal but other things in life are important.
"I need a fresh challenge and although I know I'm taking a big gamble I am ready to take that risk."
Denilson added: "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."
