Hartson: Sutton still has plenty to offer
The former Chelsea man has a clause in his contract which allows him to walk away from Parkhead in the summer if he fails to agree a 12-month extension.
Manager Gordon Strachan has already expressed his desire to hold onto the versatile 32-year-old, while Everton have become the latest Premiership club to be linked with a move for the Englishman.
