Klopp toasted a "perfect night" as Darwin Nunez hit four goals in Liverpool's 5-0 win at RB Leipzig in this past week - and the Reds boss was encouraged by his second-half outing at the Red Bull Arena.

"We need time to get used to each other which is absolutely fine," says Klopp. "It makes no sense to think he'd be at his absolute best after just thee days of training.

"The group we have is the best I've had in terms of helping those from the outside coming in to settle. A striker of his skillset will need time as it's different to what we had before.

"We played in a different way to Benfica, so for me both sides have to adapt [the player and the existing players]. He didn't score in his first two games, in 50-odd minutes or whatever, and we immediately faced discussions.

"That's a crazy world out there! He then scores four goals in a game, and we're discussing him the other way around.

"He's a really nice guy, loves being here, our Spanish community players help him a lot and is learning English already, working hard to understand the basics - it's all going in the right direction."
