I think the issue is how much the club can say about the issue. If anyone remembers the Justin Sawyer incident from way back, the club couldn't say anything as there were legal implications. I suspect the truth will come out at some point but I am pretty certain that this would be the only thing the club will say about the matter.
I have to say even though i'm really curious to know the reason why i like the stance by the club not to release the reasons why, it's like airing dirty laundry in public, there's no real need for it, it's done, they obviously did it for the good of the club, we should accept that and we move on.
Tbh clubs spend a lot of time lining up players, with what appears to be such a quick dismissal I can't see them having anyone lined up quick enough to get here soon enough to make a difference.
