Former Hibs and Celtic star Efe Ambrose 'set to leave Derby County'

He also knocked back the offer of a new-and-improved three-year deal.

After initially failing to find a club in the January window, he eventually signed for Derby in February.

However, he failed to make a first-team appearance and will not be offered a new deal by the English Championship club.

The Nigerian previously played for Celtic over the course of five seasons and has 51 caps for his country.
