Georginio Wijnaldum says Liverpool boss Jurgen Klopp has them training harder than last season.
The Reds won their first league crown in three decades last season, finishing 18 points clear of Manchester City and becoming the first side to wrap up the title with seven games still to play.
Asked how Liverpool have been able to maintain their consistency, the Dutch midfielder told the club's official website: "Because the group was together for a long time, everyone knows each other and it's basically the same as we did in previous seasons.
"The only thing we did now is, because we turned champions, you just want to give more and win it again. We train hard, like we did before – maybe even harder because we know we can't do things less because we know how difficult it is to win games and to perform.
"We just do the things we did last season, but we are sharper and more concentrated."
