The Sunday Mirror says Liverpool hope to offload Ryan Babel, Andrei Voronin and Andrea Dossena in the transfer window to free up cash for new signings.
Babel is wanted by Bayern Munich, Dossena by Napoli and Voronin is interesting Panathinaikos, although Liverpool will have to take a hit on the £18million they splashed out to land the internationals.
Benitez said: “We know at this time that we have to manage the squad and try and do some changes in the transfer window.
“Normally, players that are not playing will be looking at other options, especially with a World Cup coming up.
“There has been interest in some of our players.”
