With a number of QPR players criticised for their performances in recent months, Fernandes has admitted that mistakes have been made across the board at Loftus Road.
He said: "We are two years wiser than when we arrived. We want players that want to play for us. Players that want to win. Players who get disappointed like I do when we lose.
"It's heart-breaking for me when we lose. There is nothing I have gone through that is as disappointing as losing a football game. It hurt me when I saw some of the players who didn't feel the way I felt. In their case it should be worse because this is their job, it's their life. It wasn't a good feeling. It was probably the low point for me when I saw the reaction of some of the players. It has shocked me.
"It's an alien concept to me that someone takes someone's salary, doesn't put 100% in, thinks: 'Oh, we lost. No big deal. What club are we going to tonight?' That is an alien concept to me. It wasn't right to say anything during the season, but I noticed everything and I am a little bit wiser for it now."
Fernandes also confirmed in a statement yesterday that Redknapp will stay on as QPR boss next season and lead a promotion push in West London.
