Straq was loved because he ran his heart out every minute he was on the pitch. Everyone, including himself, knew he wasn't good enough for the standard required but his heart and desire gained respect from the fans.
I like Niasse, not as a footballer, but he just seemed to accept what the manager had said and got in with it in the u23's. IIRC he had one interview were he said he felt unfairly treated, he could have kicked up more of a fuss but he never.
But the managers job is to get the team playing, he looked at Niasse and made is mind up, as a footballer every evertonian could see he was not good enough for this club and so did the manager.
I hope he succeeds at his next club, but he's up there with some of the worst footballers I've seen at goodison
