Phillips, currently sidelined due to a broken arm, has been capped twice by Scotland and has been the subject of overtures from Barclays Premier League clubs during his time with the Seasiders.
Last August Southampton had a B£5million bid rejected which prompted Phillips to issue a transfer request at the time.
He remained with the club last season but, with just one year left on his current deal, his departure from Bloomfield Road now looks imminent.
Speaking to TalkSPORT on Friday morning, Redknapp said: "We're trying to get the lad Phillips still from Blackpool.
"I think that should get done today (Friday) hopefully."
