Coutinho and Mohamed Salah partnership excites boss Jurgen Klopp
The pair combined to score the final goal at the Olympiastadion, with Salah lobbing the goalkeeper after a brilliant ball over the defence from Coutinho, who was named captain for the match
"I think players like this understand each other," said Liverpool manager Klopp. "It's a good thing with having players of this quality. I was pleased but it was what I expected.
"The pass was nice and the finish was not too bad also."
"The new players are maybe better than people thought they will be.
"I think we said early that we want to build on the squad from last year, and that's what we've tried to do. For the moment, we're really happy.
"We don't have many injuries now, which is the best news and if we can stay fit, we can be very strong. Unfortunately, the other teams are also really pretty strong in England, so we have no choice but to be at our highest."
Liverpool secured three unreplied goals against Hertha Berlin at the Olympiastadion.
