West Brom have got Sturridge, that means they might snatch wins where you wouldn't expect in the remaining games. It's the teams at the bottom who have no match winners who will struggle more IMO. That would probably be Brighton, Huddersfield and one other. Hopefully not us if Slimani hits the ground running.
Let's say they lose to Chelsea next (the same Chelsea that lost to Bournemouth, West Ham & Palace, mind) - they're on 20pts from 27 games. So 11 games to get arond 16pts.
