I think now proven he's not just an impact sub.
I could say Niasse is the all action hero up front. A Rambo on crack. It's no co-incident Everton is a better side with him in than out. He'll go down in Everton's folklore as the man who saved Everton from relegation.
As for Niasse's critics. Perhaps a lack of imagination clouded their judgment. The fact they cannot tell a good player from bad without looking at the price tag or relying too much on hearsay to inform their opinions. Sadly, some of these people who are continuing to criticise Niasse seemed to lack the usual 'decorum' to admit they were wrong in the first place.
Above all, I salute the real Everton comrades showing their spirit in their support for Niasse. You are greatness.
