That picture is absurd really. No-one can argue objectively that he wasn't our highest performer last season individually.
As a CM, more goals than our strikers, most assists, chances created, most duels won etc. But what did we achieve at the end of the season? Nothing.
It goes to show. A player can be performing consistently well individually, but if the majority of the team is not, they're not going to be making as much of an impact overall. Football is a team game, played with 11 players. I think people lose focus on this simple fact a lot when discussing his performances here so far.
