Peter Odemwingie has blamed Roy Hodgson for starting the chain of events that has led to his unpopularity at West Bromwich Albion, the striker told the Birmingham Mail.
Odemwingie, 31, said the last four months at The Hawthorns - the time since his transfer deadline day embarrassment at Queens Park Rangers - have been the "worst" of his life.
But the Nigeria international, who claims he had been prepared to pay £1 million of his own money to secure a move to Loftus Road, has traced the breakdown of his West Brom career back to England boss and ex-Baggies chief Hodgson.
He claimed his heart had not been in the club since Hodgson publicly questioned his commitment ahead of a game against Tottenham in November 2011.
Odemwingie has been fined four times for outbursts on Twitter about his situation at Albion, and risked further punishment with comments in an interview with the Birmingham Mail.
"I've had probably the worst four months of my whole life," he told the paper. "At the moment, I don't know what the future is.
"The truth is, I wanted to revive my career because things were never the same after the interview where Roy blasted me.
"After Roy doubted my commitment things were never the same for me at the club. In the summer, I felt it was that bad for me that I was ready to quit top-flight football to just go.
"I did the job for the club and the fans and I asked the chairman nicely. I said: 'Listen, something happened in this season that I have never gone through in my playing career and the atmosphere for me is not so pleasant, so I would like to leave the club.'
"I wasn't happy that they didn't respect my decision when I wanted to call it a day, because I believed that I had done well for a few years."
