"The first 10 players were here, we have groups of five that train at the same time on different pitches obviously, far away from each other. It looked like football and that is what we want to do.
"For the boys, they had the longest break ever, around nine weeks. The international players usually have around two weeks in the summer, so we need to get used to a lot of things again. But the first impression was really positive."
Targets still to be achieved'
Liverpool's relentless title challenge was halted with the Reds needing just six more points to secure their first top-flight crown in 30 years.
It remains unclear exactly when Liverpool will get the chance to resume their campaign, but Klopp insists the return to training is key in ensuring his players are ready to fulfil their targets whenever the opportunity arises.
"We cannot play football with social distancing, obviously, but the first phase is absolutely possible and then later on we have to go to the normal things we do in a football game," he explained.
"You saw in Germany last weekend, there were proper football games. There was intensity in the games. So far, we have only discussed when we will start and all that stuff, but when we do start, there are real targets to achieve and things to fulfil. For us and other teams as well.
"That will give the games the intensity, but we have to be as creative as possible at the moment because pre-season usually starts differently.
"First and foremost, when you have a pre-season you know when the seasons starts. We don't know that at the moment, so that is of course different, and also we are not allowed to do a couple of things that we would usually do in the first few sessions.
"We just needed to start because we prepare a body for physical work. We can't start today and then start playing tomorrow. That doesn't work. We need time to get match fit and that's what we are doing at the moment."
'Preparing for proper competition'
In addition to containing the spread of coronavirus, concerns remain over the physical demands placed on players following weeks in lockdown and how this may affect the Premier League's footballing product.
Klopp has dismissed such concerns though, insisting Liverpool will do everything in their power to prepare for what he expects to be a competition as competitive as usual.
"We will be in the best possible shape we can be," he said. "You know from pre-seasons, managers usually say, 'We don't know where exactly we stand at this moment, we need maybe one, two, three or four games to know more about our situation'.
"But now, the challenge is that we all have to be ready for the first game, whenever it will be. That's interesting. Our game is, for different reasons, always different.
"You never have the same game again. You never have the same situation again. Everything can be perfect for a second, then you have injured players and you have to adapt to that.
"Now it's a situation we don't know. None of us know when we will start. The earlier they can tell us, the better it is, of course.
"But for all the teams, it's the same, and that's what makes a competition. If all the teams have the same circumstances, then you have a proper competition. That's what we are preparing for."
'I hope Neville gets some time off!'
People have had more time on their hands during the lockdown and Klopp is no different, with the Reds boss admitting to tuning into some of Gary Neville's comments throughout the pandemic on The Football Show.
Klopp joked about Neville "having an opinion on everything" in one interview this week, and now he's looking forward to football's return giving the media something else to talk about.
Asked about his comments, he said: "I usually don't watch that kind of stuff. Now, in lockdown, I obviously had too much time and I watched a lot and read newspapers.
"I don't think it's [Gary Neville's] fault. If you get asked a lot of questions, you have to give a lot of answers. But I realised it in this time more than ever before!
"Hopefully we can fill the newspapers again in the future with some different stuff, and then he can have a bit more time off! I would wish it for him at least."
