Championship strugglers Crewe have signed defender Jon Otsemobor on a free transfer from Rotherham.
Otsemobor impressed during an earlier loan spell at Gresty Road
The former Liverpool full-back, 22, has agreed an 18-month deal at Gresty Road, where he spent a three-month spell on loan from Anfield last season.
He told Crewe's website: "I have always been interested in coming back to the club. I really enjoyed it last time so I am looking forward to it."
Otsemobor is Crewe manager Dario Gradi's second signing this week.
Gradi already netting Nottingham Forest striker Gareth Taylor for the rest of the season on loan.
