"Fernando will be away with Spain and Steven also has international duty. It is not something we can stop so there's no point complaining," said Benitez.
"Top players are needed by their countries, but you don't have to ask me what I would prefer.
"Let's hope the two of them can then have a relaxing summer and be fully fit when we start again in August, and stay that way through the season.
"We have missed Gerrard and Torres too much.
"They do make a big difference when they play in the side together, which hasn't happened as much as we would have liked.
"Let's hope they can have a good rest this summer and be back for what I believe will be a better season.
"We have to maintain the levels of this season, the consistency and quality, to improve next time around.
"We have improved a lot this season, if we keep going the same way then we will be closer to the title next season."
