The Reds emphatically won their first league title in 30 years with seven games remaining.
Jurgen Klopp’s men won the Champions League in Madrid a year before cruising to their first Premier League title.
Despite enjoying enormous success in recent seasons, Milner believes Liverpool must work harder when the season resumes to extend their hegemony in English football.
“It’s a short career and you don’t want to waste a season or two seasons thinking, We were a very good team but we took our eye off the ball and didn’t deliver” the Englishman said in an interview with Liverpool’s official website.
“That would be criminal and something we definitely don’t want to look back at.”
“We have a couple of weeks to enjoy this and enjoy being champions and then, as soon as next season starts, we have to do our job, get on that field and be even better.”
“If we’re at the level we’re at now next season, it won’t be good enough."
