We are all biased in some way. I also think you're somewhat biased in support for Alves. I might be or I am sure I am biased in other players cases although I try to present a neutral opinion most of the time I post on forums. The truth however is that Alves has been performing at a mediocre level for some time now, don't think anyone can dispute that. It's sad. People might agree or not, but I certainly think that if a player is not performing at a level expected of him, then you need to bench him and try out the other options you have and give them a fair chance. Or atleast a chance, even if it's against lower half sides.
Playing a player who has been mediocre and keep playing him all the time will make him think that his performance is good, that he is doing okay, that he cannot be dropped. You cannot allow that in a team. You cannot allow a player get that feeling, mentality, because then he won't perhaps work harder to improve himself, because he may already think that he is doing well enough......
