Rafael Benitez conceded that the referee was right to award Manchester United a penalty during Liverpool's 2-1 league loss.
Benitez has backtracked his earlier statement about Antonio Valencia diving after the winger was adjudged to have been fouled in the box by Javier Mascherano although the initial contact was made outside the box. Mascherano was booked for his troubles.
But Benitez later admitted to Sky Sports News that it was a penalty.
"It appears that it was inside so it was a penalty, and Carra was there so it was a yellow card," said Benitez.
