Liverpool manager Jurgen Klopp believes his side will need to keep improving to hold off the chasing pack next season after lifting the English Premier League trophy.

The Reds clinched the title last month, but finally got their hands on the silverware after a 5-3 win over Chelsea on Wednesday.

Chelsea has already strengthened ahead of next season with the signings of long-term Liverpool target Timo Werner, from RB Leipzig, and Hakim Ziyech, from Ajax.

Klopp also expects Manchester clubs City and United to bolster their squads, but the German believes there is still improvement for his squad to make despite becoming English, European and world champions over the past 14 months.

"We should not stop, we have internal challenges to improve," said Klopp.

"We have the chance to make another step, but we have to because the others will not sleep."Chelsea is such a talented team, we had to bring everything on the pitch tonight. Man Utd, Man City (will contend), there are no guarantees for anything, but we will try."

Liverpool also beat Chelsea to lift the UEFA Super Cup to go with the Premier League, Champions League and Club World Cup, and Klopp admitted he will take time to record a special memento of the quadruple.

"We are champions of England, Europe and the world. We won four trophies, really big ones, so I couldn't be more proud," he added.

"I'm usually not a person who needs pictures but I will have a picture with all four trophies because it doesn't happen often, so we should."

Captain Jordan Henderson had the honor of becoming the first Liverpool player to lift the EPL trophy (the Reds' last domestic title in 1990 predated the Premier League era). The England stars believes the manner of victory over Chelsea, which needed a point to confirm its place in the Champions League next season, bodes well for the Reds next term.

"It's been a journey and to finish it off like this is really special," said Henderson. "After this, next season is going to be a big challenge for us."
