The problem with the keenness of Chelsea’s medical staff on Saturday was that a layman, Jose Mourinho, was proven right.
Eden Hazard wasn’t injured. He was just knackered. He stayed down after a foul by Ashley Williams for that reason.
It is often why players go to ground late in the day — boxers will take an eight count for the same reason — and Mourinho, as a football professional, knew it. When he spoke of everyone on the bench needing to understand the game, it wasn’t a sexist dig at his female doctor, Eva Carneiro.
Mourinho was simply saying that not all insight comes from books.
The moment Carneiro and physiotherapist Jon Fearn entered the pitch, Hazard would be made to return from the sidelines — a stupid rule, considering he was the one fouled — and that would leave Chelsea significantly outnumbered and vulnerable to counter-attack.
As Hazard wasn’t hurt, it was an error. Considering Chelsea’s excellent record with injuries last season it would be harsh in the extreme if the subsequent change in Carneiro’s role at the club came from this one mistake — but perhaps it is not the first time she has overstretched her authority in Mourinho’s eyes.
The doctor will have one form of expertise, but Mourinho has another, and while it is the referee who decides whether the medical team can enter the field, surely in marginal cases there has to be consensus with the manager, too.
