Pletikosa has hit out at manager Harry Redknapp for not giving him a chance.
The Croatian played in only two games during his year-long loan from Spartak Moscow and is furious that Redknapp never explained his decisions to him.
"I am disappointed and when I last saw the coach, he never even told me I was leaving," said Pletikosa.
"The least he could have done was say, "We're not going to sign you, good luck", but he didn't even do that. I was training really well but that meant nothing to him. I only found out when Carlo Cudicini's contract was extended."
