Fernando Torres will hold showdown talks with Chelsea after attacking his treatment by the club and threatening to quit Stamford Bridge this summer.
Torres delivered an astonishingly-timed swipe at the Blues hours after helping them end their agonising wait for European Cup glory on Saturday night.
The £50million man was fuming after being snubbed in favour of rookie Ryan Bertrand in the final against Bayern Munich, branding it possibly the biggest disappointment of his life.
And the Spain striker warned he could walk away if he did not receive assurances about his future role.
Torres told AS: "This season, I felt things I had never felt.
"I felt they have treated me in a way I was not expecting, not the manner for which the club brought me here.
"We have had many conversations and, now the season is finished, we will have more talks to see what happens in the future because this is not the role for which I came.
"I have been through the worst moments of my career during the season and I am not willing to relive those moments.
"There have been many ups and downs and many moments where I felt lost and I didn't know what to do and where to be.
"The ideal for me for next season is if someone tells me what's going to happen, what role will I have in the team, what function what is expected of me and to evaluate if it is worth it."
Torres did not get on the pitch at the Allianz Arena on Saturday until Chelsea fell behind seven minutes from time.
The 28-year-old won the corner that saw Didier Drogba equalise and impressed in extra-time but he was not among those chosen to take a penalty in the 4-3 shootout win, which saw Drogba once again steal the limelight.
Torres added: "Before the game, I felt it was going to be one of my best moments and I came with great desire and ambition.
"But then I had to start on the bench. I felt huge disappointment when I saw the starting line up, maybe the biggest disappointment of my life.
"In the end, I was able to play a bit and help the team.
"Right now, I do feel it's all worth it but the truth is I've gone through some very bad moments."
Torres' fortunes have improved dramatically under caretaker Chelsea manager Roberto Di Matteo after he was in danger of being branded the most expensive flop in football history.
He more than doubled his goal tally for the club in the last three months of the season, scoring seven times, including a hat-trick against QPR.
But he has remained second fiddle to Drogba, despite the record sum Roman Abramovich spent to prise him from Liverpool a year and a half ago.
