The club being in a mess as nothing to do with it whatsover; yes, confidence may affect your decision making and a stray pass may go a miss. But the lad misses all the basics of a footballer, awareness, touch, movement etc etc.
All the flops that have come to the PL, including people like Bily, still have the very basics that make a footballer; they can control a ball, they have awareness of what is around them, they can see space and know to run into. Niasse does not seem to have any of these, he's ran into people, hes ran ahead of a ball that was played to him.....its quite shocking.
Sorry Chris,it's dumb. it just is. he hasn't reached this level if he has been consistently showing throughout his career all the traits he is being damned for now. Add the mess at the club and awful form/lack of interest of some of those around him to the usual issues affecting debutants in this league and I would say it would be more rare that a new signing actually has the character to make their mark.Most players in this situation would start off poorly to varying degrees....Niasse obviously starting off worse than many.
I even remember judging Naismith after plenty of time here saying no way he is good enough, that I couldn't believe he had reached the Premier League. then, extremely belatedly he went on to show that he had way more to offer us than first thought. far from the best player we have ever had but left with a reputation light years away from the joke footballer he seemed at first. And he didn't join us with the manager, fans and players all at odds!
