I'm not getting carried away, but there's decent potential there now for them to implode.
I think Rafa's done a decent job there overall, and crucially has had the devout backing of their fans. I expected it to go tits up there eventually, once their fans tired of his pragmatism and negative football, but for once they lapped it up because of the name behind it.
The beauty of this situation is that nobody short of a Mourinho style appointment is going to be given anywhere near the same amount of breathing space Rafa enjoyed. For three years they've had a manager in the job who was untouchable, and that's served them quite well. The pressure will be right back on whoever takes over there now.
The only thing that really concerns me is if the takeover is on, and they have a high calibre manager lined up.
