HONG KONG -- Jurgen Klopp says Daniel Sturridge is in the best physical shape since he took over at Liverpool.
Sturridge, 27, endured another injury-plagued campaign last season, making just seven starts in the Premier League.
However, he did help Liverpool secure a top-four finish by scoring the opening goal in a 4-0 win at West Ham United back in May.
"It's the best condition since I'm here," Klopp said of the striker. "OK, I came in October 2015 and Daniel, I think, was probably injured. Last preseason was after a tournament and a short break.
"This year he has had a proper break and is in a good physical shape absolutely."
While Klopp told the assembled media at the luxury Grand Hyatt hotel in Hong Kong that there was nothing new to add on any potential further incomings to the club, he did stress the importance of ensuring that no key players leave Anfield this summer.
"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 added.
"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 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 we can bring into the squad. I expect a lot of progress from the players based on their experiences from the last years."
