Salah joined Liverpool from Roma last month in a club-record deal, for an initial £36.9million.
It comes after the winger had flourished in Italian football, first with Fiorentina then the Giallorossi, following an ill-fated stint at Chelsea.
Salah made just 19 appearances as he failed to make his mark with the Blues, in a move that Klopp reckons came “too early” for a player who had initially broken onto the European scene with Swiss club Basel.
“A lot of players have shown it is quite easy to struggle at Chelsea, [Kevin] De Bruyne is one,” Klopp said. “The only thing that we really ignored was what he did at Chelsea.
“He is a left footed player and we don’t have too many of them in the team. It all makes him really valuable for us.
“I’m happy for the moment. He needs to learn a lot. We brought him into the game against Wigan just to show him. That was pretty much all. Now we have to start working with him, the physical part and the technical part.”
Indeed, Klopp came up against Salah during his time as Borussia Dortmund boss and was left wanting to take the Anfield new boy to the Westfalenstadion.
However, he was beaten to the punch by Chelsea – leaving him to wait three-and-a-half years before being united with the player on Merseyside.
“We played against him when he was at Basel and we didn’t know him,” Klopp added. “We played with Dortmund against him and it was ‘what the f***!’
“It was unbelievable. The moment I said ‘let’s go for him’ he was already at Chelsea.
“Then he struggled at Chelsea because it was too early. Then he went to Fiorentina and then Roma. The question is ‘what did you not see in him?’ because he played all inclusive football.
“He was quick, he played a lot of games, he created chances and scored goals by himself.”
