Chesterfield are leading the race to land Celtic defender Josh Thompson, Sky Sports understands.
Thompson is currently on loan at Peterborough but he is yet to feature this term for Darren Ferguson's side.
Now Sky Sports understands that Thompson is set to depart London Road for another club.
A number of Championship and League One clubs are looking at taking on Thompson.
But Sky Sports understands that Chesterfield are favourites to claim his signature.
