They might be in a rut at the moment, but there's time for them to turn it around with Rafa at the helm.

Also, they have shown a will to invest (they've investested far too much on shyte, for me) which will please him as that's what he didn't get the chance to do here; build his own team etc.

Or, he could get them relegated and that's his career done over as far as the Premier League is concerned I'd say.
