Liverpool boss Brendan Rodgers says he needs to deepen his squad in preparation for the Champions League.
Rodgers believes a bigger squad will be important to his plans to ensure the team retains a freshness.
"It's one where we just need good players," he told the Liverpool Echo.
"The position we were in last summer was that we were losing players who were cover players and it was difficult for us to bring in starters.
"This year the squad will change around. We will need to change the team regularly over the course of the season in order to keep the efficiency and the energy in the team.
"Those players who are coming in need to be capable starters. They have to be to the level that we require to perform. That is absolutely key for us this summer."
