We had one fairly recently in Lukaku. I am sure that they are hard to find, but it's what we should be looking for.
As it is we have Niasse and Tosun who if they are worth 5 goals a seasons each, then they will have exceded my wildest expectations for them. DCL at least runs around a bit, and I will not judge Kean until he gets some proper game time.
Richy, Walcott, Siggurdson and the rest of them I regard as attacking players rather than out and out strikers. And unless you are Messi or Ronaldo or in that band of elite players, you're not going to be getting to those figures either, and only Richy has the potential for that and at the moment I only see him realising that if he kicks on here and then gets a move on to one of the super clubs that we seem perma-locked out of being.
Very depressing for me, but I hope that the management at Everton see it as a challenge that they can overcome and in a few seasons time I am moaning about not getting a second galactico in early doors.
