Clrnc They don't need 4, they need 3! π
Sorry dude, I'm unsettled and I'm transfer listing myself. If they draw with Spurs, they need a 4 goal margin next weekend if we're winning by one.
But to beat us, they need to improve their goal difference by 3 relative to us. Not 2. That's why I say we're at +2.
The reason I'm talking about goal differences and not goals is that in the context of goal difference, our values (the ones that go into the table) are actually sets of number pairs, that is:
GD = { d = { (g , a): g β a = d }: d β β€ }
These sets are the natural equivalence classes over the result of subtracting the second element of the number pair (a, total goals against) from the first (g, total goals for).
