Dimitar Berbatov lashed out at Manchester United manager Sir Alex Ferguson on Monday over his treatment during his final season at Old Trafford.
The Bulgarian striker last week joined Fulham in a deal worth a reported 5 million pounds ($7.9 million) after falling out of favor at United.
The 31-year-old cost United 30.75 million pounds ($48.8 million) in 2008 and was the Premier League's top scorer in 2010-11 but made just 12 league appearances last season.
The beginning of the end appeared to come when he was left out of the match-day squad completely for the 2011 Champions League final against Barcelona.
Speaking at a press conference in Sofia, Berbatov told reporters: "I don't think I deserved such treatment at United -- not playing in the last year."
"Maybe I should've gone when (Ferguson) left me out of the squad for the Champions League final," he said. "I know he's the boss, but he has lost, to some extent, my respect because of the way he treated me."
Berbatov found himself below Wayne Rooney, Javier Hernandez and Danny Welbeck in the Old Trafford pecking order last season and this summer's arrivals of Robin van Persie and Shinji Kagawa threatened his place further.
Berbatov felt he was the victim of a decision by Ferguson to play with a different style.
"I found it hard to accept his decision -- I still have my dignity. I scored many goals, I won the league two times, and I was the league top scorer, so it's not bad.
"I'll have no problems playing against United as this already happened in my career. But there's no point to look back again," he said. "I said goodbye to the people who deserve it. I couldn't say goodbye to Ferguson."
Berbatov's move to Fulham was not without controversy as he angered Fiorentina by turning down the chance to join them and then snubbed Juventus.
Berbatov defended his position, saying: "I've never personally told them, 'Yes, I'll play for you.'
"It's not my problem that someone is disappointed. After all, I choose where to play and be happy."
Berbatov's agent Emil Danchev also revealed that Tottenham made a last-ditch attempt to re-sign their former player.
