The 31-year-old arrived at the London club last night in the hope of agreeing a move on deadline day, despite not being granted permission to speak to the struggling Premier League outfit.
"He has to get on with his life," Redknapp said in a press conference. "He felt the deal was done. Let's hope people give him an opportunity [back at West Brom]."
While Redknapp has admitted that he 'feels sorry' for the forward, the 65-year-old believes that he failed to conduct himself in the right way.
"He made a mistake turning up at the ground," Redknapp added.
Meanwhile, Odemwingie has revealed this morning that he still intends to leave The Hawthorns.
