Gomes told The Sun: "Redknapp barely talked to me. I was playing really well when he hired Friedel. So I was really surprised and decided to ask him about that.
"Redknapp asked me to be calm, because I was his goalkeeper and he trusted me, as he told me. But that didn't happen.
"In the 2010-11 season, I made only two mistakes but I didn't give them so much importance and I didn't think I was going to be sacked from the team because of that."
Gomes reckons his old boss then blocked his chances of getting away from Tottenham to restart his career.
He said: "I asked Redknapp to let me go, but he said no to three offers for me. QPR, CSKA Moscow and Atletico Mineiro wanted me.
"I was close to CSKA because they wanted me only for four months and I was going to play the Champions League, but Redknapp didn't allow me to leave."
