Ralf Rangnick was trying to implement a new style at Manchester United.
The Austrian manager was hired on a short-term spell last December following the dismissal of Ole Gunnar Solskjaer last winter.
Ragnick was known for his particular style of intense high pressing but unfortunately finished the season in the sixth.
Fernandes explains what went wrong with Rangnick at Old Trafford.
“Ralf came with his idea of playing with intensity and pressing and how he was used to playing in Germany. But it did not quite work out with us because there was an atmosphere between everyone where the confidence was low and everything was really down,” Fernandes told The Athletic.
“It is really difficult to come off when you are in that run.
He continued: “It is nothing to do with Ralf. He tried his best. He is a good manager with good ideas but it did not fit with everyone. This is because the team had been built with Ole and his idea, and then a new manager comes in with [his own idea].
“That probably could be the difference at the club because every manager who has been here has had different ideas, so they bring different players in.”
