Big chance definition: "A situation where a player should reasonably be expected to score, usually in a one on one scenario or from very close range when the ball has a clear path to goal and there is low to moderate pressure on the shooter". (Penalties are always considered big chances but seeing as we only had 2 of them awarded to us all of last season it only emphasises and underlines just how fucking good we are at creating them!!!
We should convert more of these chances simply by having Solanke in the team (and by having Solonke and keeping Richie it also means less pressure for Richie to play if not 100% fit, so when he is rotated he should be even better as more injury free).
But having Solanke a proper number 9 again also means Son being played in his best position, and Solanke is able to link play which in turn means even more chances of creation and maybe goals from Son and the rest of the attacking players.
It means he improves our attacking output and our output is already one of the best in the league before he joined us.
Of course there are still loads to address and improve how we attack but Solonke alone should convert a higher % of chances, that alone moves the needle for us - turning draws and some losses into wins (Brentford, Woolwich away, even the Chav 9 man game, Wolves, Villa, West Ham x2, Liverpool away) at least 10 more points IMO.
So now we address the other major problem and that's oppo transitions against us and a 1v1 dribbly winger doesn't do this. (I still absolutely want one because we don't have someone who does this) but if we want to move the needle to make our biggest improvement then it's stopping oppo transitions becoming big chances against us.
If we've just added more goals by hiring Solanke (I'm as sure as I can be we have) and we can address conceding fewer goals (fewer big chances) from oppo transitions then we will be a better team. Focusing on a better #8 than Sarr will achieve this. (Ange's system is open as he commits many players forward so we will concede more chances than a less risk-averse team) but score 15 more, concede 20 fewer and we will be a top 3 side.
A 1v1 winger whilst absolutely needed doesn't address our biggest problem (Solanke will address us converting more chances), getting in an aggressive cunty #8 (that's why Ange likes Gallagher - people may dislike him but none of them can say Sarr is better with a straight face) will go a long way to addressing this weakness and thus make us a better side (WIN MORE FUCKING GAMES).
