The Kop manager knows Luis Suarez and Daniel Agger will again be coveted after accepting that the Reds are likely to miss out on Champions League qualification for a fourth successive season.
Rodgers said: "Even clubs that have won the league are faced with having to keep hold of their players. So there's always going to be speculation about players here and we expect that to happen again.
"I am a realist. We've got some outstanding players here who other clubs will show interest in.
"But I can only speak from my experience of working with the players here and I think they are all happy.
"Last summer was a pivotal time. A lot of players could have left, and we did lose a lot of experience when Maxi Rodriguez and Craig Bellamy left, but the rest of them decided to stay and some even signed new deals.
"They all seem happy. They seem to want to be here as we move the club forward."
