I agree Dave, Grealish is not good at all at interviews and it's very easy to spot what is written by PR people (the goodbye and the response to Preece's article on Twitter for example). This is all turning bitter and I don't think for a minute he wants it to be this way, he just isn't polished enough & some of what he says is taken out of context. "100%" means he feels he has already improved, not he's 100% better - it's a bit of daft question to be honest but he's not quick thinking enough to say "it's early days etc etc" so what rolls of the tongue is just lingo like "totally".
