Liverpool boss Brendan Rodgers says he won't allow standards to slip after last season's success.
The Reds are preparing for a Champions League campaign this term.
"Towards the end of last season, for example, when we played Norwich it was Neil Adams's first home game as manager," Rodgers told the Mail on Sunday.
"I did all my homework, as I would if we were playing Chelsea or Manchester City. I looked at how Neil's teams had played when he was youth-team coach, what system he liked to play, and I looked at his entire history as a coach. He liked the diamond system, so we played a way to counter and combat that."
