Poyet refused to condemn the 25-year-old, instead praising him for having the courage to take responsibility.
"The one who gives you everything, who is involved in everything, is the one who often makes a mistake," said Poyet.
"If you hide or are not in the game or do nothing to take a risk and try to win the game, then for sure you are not going to make any mistakes.
"That's the bad side of football.
"The ones who take responsibility and the ones who care - and show it week-in, week-out - are the ones in the position to make mistakes."
