It is not very difficult to understand. JR has a well-known injury history, has a reputation for not being very professional, and has a high salary. No top clubs were willing to take the risk. I think he has amazing skills, especially his spatial abilities, but we treat him like teenage girls treat Kardashian or Addison Rae. Football is a team sport, and is not about individuals.
If you want to play for the top clubs in the world, you must be in the best possible shape you can be in, and you must be prepared for running a lot, and many high-intensity sprints. JR is nowhere near any of this, and that's the truth. Everton have ambitions, and then we have to build a solid training culture.
Then we must first and foremost get players, who of course have quality, but who also can withstand a lot of training, and who have the mentality to do so. We can not pick up players who lack this drive, and who are more often with the physiotherapist, than on the training field.
Do you think Guerdiola had trusted JR against PSG, or Tuchel when Chelsea met Real Madrid?
