Television pundit Ian Wright had labelled Luiz a â€ścowardâ€ť for the challenge, which came with Chelsea already four goals up.
Benitez said: â€śI see hundreds of tackles in the league that are more dangerous than that one. I wonâ€™t say it wasnâ€™t bad â€“ it wasnâ€™t the best â€“ but a factor was the size of the other player.
â€śDavid Luiz is a great player and we have to be pleased heâ€™s playing in the Premier League. It was bad luck.â€ť
