Liverpool boss Jurgen Klopp admitted frustration with their defending after defeat to Bayern Munich in Singapore today.
The Reds lost 4-3, with Cody Gakpo, Virgil van Dijk and Luis Diaz scoring for Liverpool.
Klopp later told liverpoolfc.com: "Was I surprised about the intensity? No. I think it was pretty clear when you set up a game in that period with two teams who are pretty competitive, two managers who are pretty competitive then I think it's pretty clear that it has to be intense. I saw a lot of good things, but of course some things which I didn't like and now we have to make an analysis.
"That's always in pre-season the same: we need to have a look what is really physically, because we did a lot in training and yesterday a lot in really tough circumstances. And you saw the goals we conceded were mainly lack of concentration in the moment twice. A very similar situation, the first goal we conceded and I think the fourth, were very similar. It's obviously not allowed but it can happen anyway. We have to analyse it properly, I have enough time to do that on the flight home.
"And the atmosphere was great, I said it outside. The people created something really special, we felt from the first second super-welcome. That's intense as well! People were waiting everywhere for us, I understand that. But I will not miss opening a door and everyone is cheering, to be honest! I'll be really happy if I can open a door at home and nobody is cheering! Good.
"I hate losing, I feel that all the time when it happens, I really feel it and today is the same. But pre-season, strong opponent, we could have scored a fourth as well obviously; Bobby Clark had a really nice situation with Ben Doak, other situations as well. So, a lot of good stuff, stuff to improve. That's how it is, let's keep going."
