As it stands now, even if Sheff Utd were to lose, they will be
safe as long as they don't lose against Wigan on the last day. But
if they do lose, West Ham need at least a point against Man U
because their lose out to both Sheff Utd and more importantly,
Wigan on goal difference.
And so far, Charlton has yet to play Tottenham. If they win, it
would make this very interesting.
