Fuck me you are one repetitive boring old fart.
Chelsea's scorers this season.
Costa 13, Hazard 8, Moses 4 then five players on 3 goals.
Liverpool's (one game less).
Mane 7, Origi 7, Lallana 6, Coutinho 6, Firmino 6, Milner 5, Sturridge 4, Can 3.
Whether Chelsea win the league or not is more than likely not going to be down to Costa but their defence (even though they have been as lucky as hell a few times this season with not conceding when their opposition threw away great chances). They are far more reliant on their two top scorers being available and avoiding serious injury / suspension / loss of form, than we are.
Certainly if Costa were to be out for any length of time then you wonder how they'd manage, that can not be said of Liverpool as we seem to be scoring just as many without Coutinho & Sturridge available, as with.
