People will not be on his or any other players back if they perform to a decent level. If a player isn't performing then of course people will talk about, just like they would if a player performs well, like he did yesterday. It's understandable that players don't always perform well because of various factors, but you can still demand more at times. Players and people in general will always be judged on how good/bad they do, it's just the way it is, whether thats football or any other job.
