I am obviously gutted that Jones is looking extremely likely to join Rangers (if he hasn't done so already). Nevertheless, I would rather have Jones deciding to leaving the club now, than leading the club down the 'will he or won't he' scenario of signing a new deal, before leaving the club at the end of the season. Regardless, we now have time, if we haven't done so already, to draw up potential replacements for Jones and maybe even try to convince Rangers to pay some sort of money towards getting him early.
If Jones leaving early can allow us to use up his wages and any fee we could perhaps get from Rangers, in order to try and sign Stewart, then so be it. If Jones remains until the end of the season, hopefully he can continue his good performances and help us to challenge as close to the title and 3rd place as we can (even it might just be to impress his new employers). Hopefully fans can remember him for his good performances and not for him leaving us in this way.
