Liverpool manager Jurgen Klopp admits the club could not have predicted the success of their attacking trio.

Roberto Firmino, Sadio Mane and Mohamed Salah have scored 250 times under Klopp since 2017.

With Salah expected to make his 150th appearance for the club against Arsenal on Wednesday, Klopp said: "First and foremost, that means he played 50 games a year, each season, 50 games, and still counting. Unbelievable. That's a big number.

"Obviously he was lucky and we were lucky that he could play all these games, because he was not injured, which is good.

"I was very positive in the moment when it was clear that we signed him. I remember our talk, when we first met face to face, when we spoke.

"'What's your favourite position?' 'It would be right wing, but Sadio Mane is playing there and he played a pretty good season.' 'Yes, he does, but he can play the other wing as well.'

"That was pretty much the start. The idea was clear how we want to play with the boys up front, but it worked out in a manner which we couldn't have expected. They scored now 250 goals since they [joined the club], that's an incredible number.

"It was a good day for Liverpool [when Salah signed] and a very good day as well for Mo because it fits really well and that's very important in life. You cannot change the world alone, but together, with the right people around you, you have a better chance to do it."
