Aguero and Jesus are not out and out strikers!
Kane I agree with, he seems to be an anomaly these days, proper old school striker but he does have good all round play.
Lacazette and Aubamayang play as forwards rather than proper strikers.
Morata is pretty meh and they still really on the likes of Hazard for goals.
Lukaku is strugglin, probably because he is another who's all round game is not quite good enough. He will generally get goals but does he bring others into play?
Messi, Ronaldo, both not traditional strikers either.
All I am saying is having a proper striker does not solve the issue of our other players messing up in good positions. Its not like our centre forward (Richarlison or whoever) is missing chance after chance and the team is geared up to providing that player.
