IF we lose all 3 then Saints and Swansea will only need to win 2 each. Agreed they're more likely not to but when teams are fighting for survival past form means very little.
I'm not sure how any seasoned supporter of a team in our current position could not have at least a tiny doubt that things could go tits up over the final 3 games. Stranger things have happened than Saints winning a couple of games and after Man C and Liverpool our GD may not be looking so good...
