The Manchester City captain has endured a difficult campaign littered with errors, leading many to suggest that his career has already peaked.
But the ridiculously high standards he has set for himself over the years mean that every single mistake he makes is guaranteed to come under intense scrutiny.
Kompany has been on a horrendously poor run of form this season and it has mirrored City’s, who have won just five out of their last 15 games in all competitions.
The Belgian defender has made countless individual errors which have led to the opposition scoring, with the most high-profile mistakes coming in the defeats to Liverpool and Barcelona.
He has looked more rash at the back than ever before. Basic positional errors combined with a sheer lack of discipline are at the root of the problems.
The 28-year-old has been found out of position and out of sync with his defensive line far too often, while his usual calming influence has turned into one of panic and desperation. Many strikers have worked him out; his tendency to dive into duels is getting him into trouble.
The raw statistics back up these statements. Kompany is averaging fewer tackles (1.5) and clearances (4.2) per game than at any time during his spell at City. His interception tally of two per game could also be improved upon.
He is committing more fouls (1.5) per game and has received six yellow cards in the league, which is again more than in any other season since he has been at the club.
To compound his misery, he was stupidly sent off for Belgium during the international break, meaning he is suspended for the crunch clash with Wales in June.
Kompany must still be regarded as a top-class defender, one who is suffering from a severe loss of form, but if his error-prone, ill-disciplined nature continues, it must be seen as a constant rather than an exception. City must hope his career has not already peaked.
City’s leader must return to the form which saw him gain the reputation as one of the best defenders in the world as quickly as possible, starting with the crunch clash with Manchester United on Sunday, because he has cost them far too many times already this season.
