AC Milan are rumoured to have offered £3m to QPR for the midfielder after he spent six months on loan at the Serie A club last season.
"He wants to move," Redknapp told reporters in this morning's press conference. "We just need a club to come in and pay the money that the chairman is looking for.
"Adel hasn't done one day's training since we got back in pre-season. He just needs to get fit, whether he's here or not."
Taarabt has one year remaining on his contract with the recently-promoted Premier League side.
