Looking at all 20 PL clubs, it's hard to see where else he's going. The top 6 are a no, other teams seem happy with their manager (Burnley, Leicester, Bournemouth, Brighton) or are too small (Huddersfield, Swansea).
Unless Everton or West Ham quickly give up with Allardyce and Moyes, it only really leaves Southampton, Watford (if Silva leaves) and Palace (if Hodgson retires). All quite far from his Liverpool family home.
