Jurgen Klopp highlights points Liverpool needs to improve after Borussia Dortmund's defeat

Jurgen Klopp said Liverpool needed to improve after his team collapsed in their first pre-season loss thanks to neglected mistakes.

The defending European champions were beaten Friday night by Borussia Dortmund, the former Klopp team, at Notre Dame Stadium in Indiana during their first match of their American tour.

Each of the three goals conceded by the Reds could have been avoided without a slack game.

For the first goal, Nathaniel Clyne did not clear his lines, the second followed hesitation from a half-open corner and last goal when young left-back Ybader Larouci conceded possession. balloon in his own area.

The Reds had already beaten Tranmere 6-0 and Bradford 3-1 in the first run of the British preseason.

After the match, Klopp said: "The goals we conceded were due to a lack of organization in the situations. When you change the alignments of your teams, it is difficult to have this organization.

"It will be better in (rest of) pre-season and the season must be.

"There were a lot of good things and some things I did not like, which is normal in pre-season. I decide what we do in training and I know what we did on Thursday in already very mild weather conditions.

"I still do not like what I see, but I know the reason.I'm not in heaven when I think about our performance, but I know that there is still a lot to do . "

The second and third goals of Dortmund were scored at the start of the second half after many changes to the break.

However, Liverpool left his home team on the field for an hour before replacing everyone except goalkeeper Simon Mignolet.

Klopp admitted that this had contributed to the eventual defeat of the Reds.

"We had to do the same team for the first 15 minutes of the second half and Dortmund could change and turn around the bar, and that's what I would say, in my opinion," Klopp said.

"There were many good football moments. You can see that they are a little further in pre-season than us, but we had to fight and defend those situations.

"There were a lot of good things, but the goals of Dortmund, the first and the second, the second ball after the corner. We scored our two goals, which was really good, especially the first, and we had opportunities.

"What we could learn is that other football teams also have very good players. Obviously, Dortmund has a lot and has had a lot of solutions. Almost all positions are of the highest quality and have a very good team. It was pretty impressive. "

However, Liverpool could reap some benefits from the loss as young striker Rhian Brewster scored his fourth goal in three games and Harry Wilson also scored.
