Ruben Amorim would appear to be a massive gamble for a club that needs first to fight a relegation battle, before worrying about Europe and if we'll be seeded for the Champions League.
The PL is the most unforgiving league in the world, it consumes most managers. Walking into a big club, with no experience of the league, not speaking the language of the media and the fans would be a massive, massive challenge.
They'd be mad to appoint him.
