No mention of Gleeson.
Hudson certainly alludes to wanting players with the right stuff, and has clearly been frustrated with the poor attitude/unavailability of some players (Roux, Kosta, Smith etc) at different times.
I guess with that he can only be applauded.
Again I'm just guessing but something happened with Gleeson on that Mexico/USA trip, that didn't impress Hudson.
