Less than 24 hours after winning at Wembley the reds were well beaten by Bundesliga side Mainz 05 in Germany.
The wisdom of playing a friendly within a day of a game against Barcelona had surprised many - but it seemed the rebranding of the Opel Stadium and the return of Klopp to his former club was a marketing exercise that Liverpool couldn't turn down.
It was a heavily changed side from that which beat Barcelona - a total of 9 changes to the starting XI with Alex Manninger taking charge of goal. Matip and Andre Wisdom formed an unlikely centre-back partnership - with Moreno and Alexander Arnold at full back.
The reds went behind in the 15th minute when the home side were gifted a penalty - the decision of handball going against Andre Wisdom.
On the stroke of half time the German side added another - Manninger easily beaten on his near post.
Marko Grujic was subbed off during the first half with what appeared to be an ankle injury.
Some changes at half time - with youngsters replacing some legs that needed protecting. Portugese 17 year old Toni Gomes amongst those wearing the senior shirt for the first time.
Kevin Stewart was caught out a number of times in the centre of the park and just before the hour - it was all so easy for Mainz to move through the non-existant midfield and make it 3.
A fourth goal was headed in to complete a miserable afternoon for the reds.
The friendlies are over - the real action starts next week with the beginning of the Premier League.
