Yes the distribution of goals scored is interesting too, some 6-1, 7-0 trashing or we had 8-0 last season (?) too is making the stats look very good end of season, but in the 9 lost PL games last season we only scored 7 goals. And conceded 20.
5 of those was only a 1 goal loss, and in all we had enough chances or even more then the opponent but we could not finish them.
(3 draws we had, all of them 2-2, we had so many chances to score more than 2 in them for example City-Spurs early on which could have been 5-2 really)
Makes a big difference instead of couple 6-1, 7-1 only do 4--0 wins but you add the two extra goals to our losses/draws and we might have 10-12 points more while some rivals a couple less if its against them. Same number of goals scored but different points tally in the end.
Leeds will be interesting, they can play crazy scorelines, they will put our defence under pressure and 99.9% sure they will score at least two goals imo, but we should have more space too than normally to create chances.
