The Spaniard said: "We are playing too many games, games each three days. You have to manage your squad.
"Some players have fresh legs and you can play them.
"We can manage in the three competitions. We know we can do it.
"But if we feel we need to prioritise something we will do it."
When asked if he was tired, Benitez joked: "I was not running so I am fine.
"I am disappointed because we could not win. I am just thinking about the next challenge."
