Salah ended a four-game goal drought with the winner at Huddersfield on Saturday and looked more like his old self in scoring either side of half-time.
Roberto Firmino and Sadio Mane were also on target as Liverpool's prolific front three that led them to the Champions League final last season all scored in the same game for this first time this campaign.
"It's good that we can maybe stop talking about that a little bit," said Klopp. "I was not in doubt, he was not in doubt, but if you are constantly asked about it, you think something is up."
Salah has reached his half-century quicker than any other player in Liverpool history after just 65 appearances for the Reds.
"It's great, I'm happy to score my 50th goal," said Salah despite his muted celebrations.
"We know how to play with each other and know our qualities," he added of his combination with Firmino and Mane refinding its spark.
Liverpool are now back on top of Champions League Group C as Paris Saint-Germain and Napoli drew 2-2 in the French capital, but all three sides remain separated by just two points.
"We are not through yet. This group obviously stays exciting until the end, I think that was clear from the draw," added Klopp. "But you cannot do more than win your own games."
Barca cruise past Inter without Messi
Rafinha replaced Lionel Messi and helped Barcelona win without him as the Brazilian scored the opener in a 2-0 Champions League victory over Inter Milan on Wednesday.
With Messi out for three weeks and Real Madrid next up at the Camp Nou on Sunday, the question was whether Barca could cope minus their star player and captain.
The answer may not have been resounding — they lacked some punch before Jordi Alba added a late second — but this controlled performance will certainly send them into the Clasico with a spring in their step.
"We needed to step up given the absence of Leo," Ernesto Valverde said. "It was in the head of us all." Luis Suarez, Arthur Melo and Philippe Coutinho were all excellent in his absence.
Victory all-but secures Barcelona's passage to the Champions League last 16 too. They have nine points from three games and now sit top of Group B.
Messi was watching in the stands with his son Ciro and his fractured right arm in a sling. As soon as the ball left the centre circle, the fans sang his name.
Barca had drawn with Athletic Bilbao in the only other match this season he had not started, and that could have been a defeat were it not for him setting up the equaliser.
Even the club had posted an article on its website this week entitled "no need to panic", detailing their "not so bad" record without him.
