QPR's relegation was confirmed on Sunday when they drew 0-0 with Reading, who will join them in the Championship next season.
Despite ploughing millions into the club to fund the signings of Park Ji-sung, Jose Bosingwa and Chris Samba among others, neither Harry Redknapp nor Mark Hughes could get enough out of a squad that was expected to be challenging for a top-half position this season.
Fernandes, who confirmed that Redknapp would stay on as manager for the Championship campaign ahead, has bit his tongue all year about the team's poor performances, but let rip at the players who he thinks have let the club down badly.
"It's heartbreaking for me when we lose. I don't want to go out, I just want to stay at home," the QPR owner told the club's website.
"And I am someone who has dealt with success and dealt with disappointment. But there is nothing I have gone through that is as disappointing as losing a football game.
"I haven't said it throughout the season because it wasn't right to be said, but it hurt me when I saw some of the players who didn't feel the way I felt. And in fact, in their case, it should be worse because this is their job, it's their life. It wasn't a good feeling."
