"We know the game tomorrow is not going to be the same as the one in Cardiff," said Benitez.
"I will decide today whether to rest players. I must see how the players are, but it will be an idea to give some players a rest.
"We have to be careful. We have played a lot of games recently and I need to watch the training sessions to see which players are fit and who needs a rest.
"Some players have played a lot of games and we have another match on Saturday. It's not easy for them to play so regularly."
