The Reds midfielder admits the club were struggling early in the season but says the German boss has changed "everything".
Liverpool midfielder Lucas Leiva has outlined just how extensive the impact that Jurgen Klopp has had on the club has been this season by claiming, as quoted by the Daily Express, that the German boss "changed everything".
The Reds had won only three of their first eight Premier League matches of the campaign under Brendan Rodgers when the club acted to dismiss the former manager and replace him with Klopp in October.
Since the arrival of the ex-Dortmund boss, the Reds have reached the final of both the Capital One Cup - where they lost on penalties to Manchester City - and the Europa League, and have won seven of their last 11 league matches, losing only four of their last 20.
Lucas, who with nine years at Anfield under his belt is the club's longest-serving player in the current squad, believes Klopp's impact at the club has been immeasurable and will start to truly be seen in the coming years.
The Brazilian said at the club's end-of-season dinner, as quoted by the Express: "We had a difficult start to the season but the change of manager changed everything. Jurgen is full of passion and everyone is trying to do exactly what he says.
"In seven months we have got to two finals and hopefully next week we will bring back a trophy. I can see a lot of good things for Liverpool in the future. The future is very bright for this club and everyone is excited to be a part of it. I am no different.
"We’re getting results and confidence is really high. I want to be a part of winning trophies for this club."
Liverpool face a hectic week before their campaign draws to a close, as they host Chelsea in their final home game of the season tomorrow night before a trip to West Bromwich Albion on the final day of the domestic season three days before their showpiece Europa League final in Basel.
