He doesn't have depression, he's got manic depression/bipolar. It's completely different and as someone who once had a manic episode you've got no idea how out of control and out of touch with reality it makes you. It was F**king awesome tbh, I was the king of the world
Anyway I'm sure Mata is just S**t stirring.
As for Smith he'd be a great back up and could be a good half but we seem to have two good prospects already in Hodgkinson and Cherry Evans.
