The more I think about it, the more it's clear that his failure here was due to a combination of things
- Physical decline compared to Barcelona and Arsenal days
- Technical decline
- Both Mourinho and Ole weren't specifically interested in helping him adapt to their system
- Lack of willingness on Sanchez's part to adapt to the systems that these managers used
- Pressure of the fee and the wages
- Difficulty to develop a better on-pitch relationship with his teammates and possibly on a personal level aswell
When you put all these things together...
Yes, ultimately Sanchez is the one who should be criticized for his performances here, but the circumstances hardly helped.
