Salah has out up some brilliant stats for the Reds since moving from Roma in 2017 but has been criticised at times for his selfishness.
He helped the team win the Champions League last term and they are all set to claim a first Premier League title after moving 22 points clear at the top.
But former England and Tottenham striker Darren Bent reckons Liverpool can improve on Salah to help them get even better.
Paris Saint-Germain sensation Mbappe and Borussia Dortmund’s England star Sancho have both been linked with moves to Anfield and would be seen as an upgrade.
Bent praised the numbers that Salah is putting up but claims that he is too selfish unlike teammates Sadio Mane and Roberto Firmino.
The pundit does not think Liverpool should sell Salah unless they can get a top-class replacement straight away.
But he named both Mbappe and Sancho as two players who could fill that role on the right for Klopp.
“Listen, we know [Salah] scores a lot of goals and he is a top, top player,” Bent said on talkSPORT.
“You look at the accolades, two Golden Boots, player of the season, Champions League winner, about to be a Premier League winner - the accolades are there.
“But when you look at his general play [compared] to say Mane, I’d have to say Mane has been better than him.
“He may score more goals than Mane but Mane’s work-rate for the team, he’s unselfish, always looks for others first, he’ll get his fair share of goals.
“So you’d have to say Mane, you can’t sell Mane, he’s so important.
“Firmino, we know he doesn’t score that many goals but he’s like the glue, he links it all together. His hold-up play is arguably one of the best in the league, brings players in, holds onto the ball. He’s fantastic.
“So you look at Salah and yes he does score all these goals but is he really complimenting Mane and Firmino or is he looking for more goals?
“Because I’ve seen certain situations this season where he should pass it and he’s shot and you can see the frustration starting to build.
“Listen, it’s not about selling him and getting nothing, like getting £100m that’s it.
“But if you can replace him with like an Mbappe or someone like a Jadon Sancho, I think it’s worth thinking about.”
