Real Madrid decided not to attend the gala after learning that Vinicius Junior had been beaten by Manchester City midfielder Rodri to the award.
Tebas slammed Real in the immediate aftermath and also said on Thursday: "I think that Real Madrid lacked the chivalry that has always been one of its hallmarks and is part of its anthem as well, shaking hands when it loses.
"A lack of chivalry that has been lacking for some time. It didn't surprise me. It was a childish attitude, a hotheadedness, call it what you want. It was already seen in the attitude of Real Madrid TV with the videos.
"We see a supremacist behaviour that everything has to revolve around them."
On the strength of the LaLiga, Tebas declared: "Ronaldo and Messi left, nothing happened. We continued selling our television rights, we even sold more. It is true that the players help, but they are not essential. The clubs are essential."
