Hull have two very winnable home games coming up (Burnley & Sunderland), with home games against Villa & Liverpool – the game against the Scousers is on the last day when they will have nothing to play for – Hull should get a minimum 7 points from those fixtures.
West ham host Sunderland this Saturday, and I expect a home win. The game against Wigan on 24 April will probably determine whether West Ham survive or go down. Their last game is against Man City, who will probably have 4th place sewn up by then. Again, they will be targetting 7 pts minimum.
Wigan should be ok as long as they beat Pompey and avoid defeat against West Ham and Hull. They’ll get nothing from Arsenal & Chelsea. With 3 of your 5 games against sides below you, if you do go down then its of your own making.
