Liverpool boss Jurgen Klopp believes he can take his star players to a new level next season.

Klopp is confident the best is yet to come from Philippe Coutinho and the likes of Roberto Firmino and Sadio Mane as Liverpool look to build on last season's fourth-placed finish.

“Not with only Phil, but it's a good thing to talk about in the transfer window because the world thinks improving is only about bringing in new players," he said.

“Nobody thinks that the players we already have will make the next step, which is also a nice idea.

"We use the transfer window, of course, because it gives us an opportunity, but the main thing I think about is how we can make the next step with the players we had last season.

“The good news is that actually we didn't lose - and we will not lose - a player we want to keep this summer. That's the best news actually and then we'll see who can bring into the squad.

“I expect a lot of progress from the players based on their experiences from the last years."
