In the case of Robinson, he's chosen to turn up everywhere talking about his time at the club. If he wants to talk about staff who are still at the club, that's up to him, but do you doubt for a second this is all being said to suit his own agenda?
As for current players going on telly to give opinions on teams, players and managers they're due to face, it's gonnae be a case of they say nothing, or something, and that something will piss somebody off, whether it's at Motherwell or elsewhere. They want the money, that's the trade off.
