Would Clark be due a testimonial year next year. From memory there is income tax exemption for testimonials which could be a nice bonus.
I am not suggesting that the club offer a contract less than what Clark is worth but might help sway a decision if there are comparable contracts on the table.
I suppose the only other factor would be is another club was prepared to table a longer term contract that would provide longer term security
If we do turn into a team capable of challenging for silverware then one player that I would like to see win more trophies in his time here would be Clark. During the tail end of the TS era and the Price era he was one of only a few players that i thought never really deserved to be on the losing team.
