"I am surprised and a little shocked the chairman of Southampton has not phoned and kept me informed," said Mandaric today.
"We have engineered good links with Southampton since we have started meeting each other again on a regular basis and I would have thought that counted for something."
But Redknapp added in a bitter outburst: "Don't believe everything Mandaric says." Southampton chairman Rupert Lowe said: "There have been accusations that Harry's appointment was agreed before his departure from Portsmouth two weeks ago.
"Nothing could be further from the truth. We first discussed his appointment two days ago."
At the time of his resignation Redknapp said: "I will not go down the road - no chance." He also claimed he needed a break from the game.
Redknapp's relationship with Lowe is set to become one of the most unlikely partnerships in football. He looks set to take Kevin Bond and Joe Jordan with him to Southampton as his coaching staff.
