The difference is when we needed to defend well we could.
There's no doubt our defence then was better regardless of the stats, the fact is we have a lot of possession these days, we didn't use to so naturally teams would have more chances to score.
If a teams attack more naturally they will also score more, technically we weren't as good but defensively we we far superior.
We didn't have the old 1-0 to the Arsenal song for nothing.
