Derby County chase Barnsley defender Jason Shackell

Shackell has played 46 games for Barnsley this season

Derby County are keen on signing Barnsley centre-half Jason Shackell, BBC Radio Derby reports.

The Rams have approached the Tykes and are thought to have made an offer for the 27-year-old.

But managerless Barnsley - who are in talks with Rochdale boss Keith Hill - have said they will not consider any offer until a new manager is appointed.

Shackell only joined Barnsley from Norwich last summer and has two years to run on his current deal.
