I find the club's treatment of these players shockingly bad and totally unprofessional, they were signed in good faith and in the case of Sparrow played for several years, the other two were barely given a chance and now are not even listed as first team players on the website/programme.
If Gus thinks he can force them out to cover up his poor judgement of signing them in the first place and then discovering they don't fit his requirements, I think he may have a fight with the PFA. They do not deserve to be treated like this (whatever may have gone on behind the scenes) and I doubt the rest of the dressing room are impressed with the club treating contracted players in this manner.
