Maybe like the team sheet is put up for games, the current incumbent feel the retain list is similar and that when that is posted up then it is informing the players at the same time.
I am sure Liam before he went would have marked his card, and I have to say when I saw him walking round the pitch after the Ipswich game he had the look of someone who was saying his final goodbyes.
I do agree, it seems strange if someone didn't have a word with the leaves, but Football has become a cut-throat business and players are generally well paid and looked after, and maybe this is just a sign of the timers when contracts finish.
