I know nothing, but could be both. He may not have got involved much in day-to-day training himself (always rings alarm bells for me) while telling his coaches to over-train tne squad.
Impossible to say, but I was never comfortable with OG, maybe it was just his lack of personality or maybe because his initials stood for Own Goal, I don't know.
I feel strangely happy with Sami tnough, with no evidence whatsoever. Maybe it's just that I liked him so much as a player.
