Fairness doesn't exist in football mate, never did. Wenger for example with Podolski, scored 2 in 1 match, benched the next. Same with Pep, Shquiri(speling) plays well=> benched anyway eventually had to leave. No manager is truly fair in football, no one admits it but as a human, naturally they all have their favorite. For example it is clear that Ramires was a Jose favorite last season, played badly yet still being used as starters in many other games. It is the same this year with Cahill. Even Sir Alex wasn't fair with everyone, Pogba the clearest example. He insisted on playing the likes of Cleverley, Anderson...etc
