Because City are on track to score 120 goals, and it seems pretty arguable that those points we're dropping might be saved by a forward who takes his chances more consistently?
Jesus had an xG of 0.82 last time we dropped points, and failed to slot home some gettable chances. If anything we're lucky that his 9 match finishing crisis hasn't cost us more.
I'm talking about what it'd take to win the league, not just "giving it a good go", score 90 goals, have a few good winning runs, redefine the commentariat's perceptions of Arsenal or whatever. Despite this Arsenal side being consistent, dominant, well organised and packed with talent, the way I see it we're not set up win it all based on just such fine margins.
