Robertson admits it would have been “a long summer” for Liverpool players had they not won the Champions League back in June.
Despite that Champions League triumph, Liverpool left-back Robertson says it “still hurts” that the Reds missed out on the Premier League title by a single point to Manchester City last season.
What that European triumph has done, however, is ramped up Liverpool’s hunger for silverware, and they have since gobbled up the UEFA Super Cup and FIFA Club World Cup.
Liverpool fans everywhere are hoping those trophies are merely appetisers to the main course of a first league title in 30 years.
And Jurgen Klopp’s side visit second-placed Leicester City on Boxing Day hoping to extend their lead at the top of the Premier League to 13 points.
And Robertson says last season’s near miss has been a driving force in building such a whopping lead.
“Our total of 97 points wins 95% of the Premier Leagues in previous years,” the left-back told the Liverpool Echo . “Unfortunately we were in the year where it wasn’t enough.
“For us, that still hurts, missing out after such a fantastic season. It was eased by winning the Champions League and we can look back and say it was a successful season.
“Without the Champions League, though, we couldn’t. It would have been a very long summer.
“We know how important every single game is because every point and every win and last-minute winner and clean sheet last season was so important. We fell short but pushed Man City all the way.”
Due to their involvement in the Club World Cup in Qatar, Liverpool have played a game less than Leicester and third-placed City.
But even with the Reds enjoying a game in hand, Robertson knows if they drop points their rivals will be ready to try and capitalise.
He added: “This season, we have got a nice lead just now, but we know if we drop points then the two teams behind us will be ready to pounce.
“We just need to keep them at arm’s length, and if we keep doing that then we keep that gap. That has to be our aim.
“We know it’s going to be tough and realistically games are going to get tougher, and if we do drop points then it’s all about bouncing back. We have done that so far.
“Against Manchester United we drew and recovered straight away and have gone on a good run of winning games. Returning from Qatar, we have to pick up where we left off.”
