Redknapp poised for Saints Southampton are set to unveil Harry Redknapp as their new manager at a news conference at 1500 GMT on Wednesday. The former Portsmouth boss replaces Steve Wigley, who has been relieved of first-team duties after just one win in 14 league games in charge. Redknapp, 57, quit his Fratton Park position on 24 November and vowed: "I will not go down the road - no chance." Pompey coach Kevin Bond is poised to join Redknapp, who will be Saints' third boss of the season. Redknapp's first game in charge will be at home to Middlesbrough on Saturday. Portsmouth chairman Milan Mandaric said he was "disappointed" by the news and claimed Redknapp had been in talks with Southampton for "some time". "It would appear that negotiations over this have been going on for some time," Mandaric said on Portsmouth's official website. "I am surprised and a little shocked that the chairman of Southampton has not picked up the phone and kept me informed." According to Mandaric, Redknapp vowed he would not join their South coast rivals when he left Portsmouth. "I said to Harry 'I hope you don't go to Southampton', and he told me 'absolutely not'," he said. "I'm wouldn't say I'm bitter, disgusted or angry, just disappointed, but it's Harry's life and it's his decision." Redknapp became a cult hero after leading Portsmouth into the Premiership for the first time, and then masterminding their survival in their debut season. But he left the club claiming he needed a break from football, though many believed he was upset with Mandaric's decision to bring in Velimir Zajec as executive director. Southampton chairman Rupert Lowe was desperate to give former academy director Wigley, who replaced Paul Sturrock just two games into the season, every chance to succeed at St Mary's. But results under Wigley have been poor and Southampton are deep in trouble near the foot of the table. When Redknapp's appointment is confirmed, he will be Saints' ninth manager in eight years.
