Alexander-Arnold appealed in vain for offside for Uth's strike however it was his staggering free-kick that had the more noteworthy effect for Liverpool, who survived an early punishment when Simon Mignolet spared a good effort from Andrej Kramaric.

He has still a few things to learn. He thought it was offside yet it was clearly not offside, sadly. Trent is an extraordinary player and I need to state I would preferably have 2-1 than 1-0."
Emre Can and Alberto Moreno both molded to take the free-kick before Liverpool's homegrown appropriate back cleared the ball past Oliver Baumann. Furthermore, Klopp conceded: "He took it since I revealed to him he needs to do it. I don't assume acknowledgment for the free-kick since he takes them superior to anything I ever could. Be that as it may, I looked the greatest number of under-23 diversions as I could last season and he took a large portion of the free-kicks at that point. The objective is a similar size regardless of the possibility that the wall is not as tall. There is dependably a major test amongst him and Ben Woodburn with free-kicks subsequent to preparing for the next match. It was great. He was fortunate the wall didn't hop yet it was a critical minute for us."
Alexander-Arnold, who grew up near Liverpool's preparation ground in West Derby and joined the club's foundation matured six, reflected: "It is a thing of dreams to make your European presentation for your childhood club and to make it with an objective was extremely exceptional for me. I got egged-on to take the free-kick, frankly. I never put my hand up first yet I had the certainty to take it and it paid off."
Klopp said Liverpool had permitted Hoffenheim posssession in unthreatening zones in the course of the game, a view that did not run down well with his inverse number. "I don't concur," countered Nagelsmann. "We had the ball in numerous critical spaces.He needs to state that and safeguard his group. He can't say, 'Hoffenheim played incredible and we were crap.'"
