Derby County are reportedly keeping tabs on Charlie Mulgrew's contract situation at Scottish champions Celtic.

Celtic defender Charlie Mulgrew has reportedly been added to Derby County's shortlist of summer transfer targets.

The 30-year-old is due to become a free agent in the summer when his contract at Parkhead expires.

He recently revealed that talks over fresh terms were underway, but no agreement has been reached.

According to the Scottish Sun, that has alerted English Championship outfit Derby.

Mulgrew rejoined the Bhoys in 2010 following a spell with Aberdeen.
