Of the listed, Aguero by some distance. Kane's currently effective but there's something about him that I simply cannot warm to - probably that he looks and sounds like a posh Trump offspring. Lukaku is showing what happens when you get the service he was often lacking at Everton, and does anyone on here seriously expect me to vote for a Chelsea player? In truth, I still believe that the best striker in the PL is Sanchez. I know there's been all the crap about will he move / will he play / where will he play but when he's on his game he's as good - if not better - than Aguero in my mind.
I appreciate Morata is the scum of the Earth now but I think he's been brilliant in a very tough situation at Chelsea to fill Costa's boots straight away.
