A former Premier League star is of the opinion Mohamed Salah is the third best player in the world, ranking "just behind Cristiano Ronaldo and Lionel Messi".
With Liverpool having lost some of their best players in Luis Suarez and Philippe Coutinho to Barcelona in recent years, former Reds star Luis Garcia has warned the Anfield outfit that failure to win trophies could result in Salah eventually leaving the club too.
"If Liverpool win trophies, then I think it will be much easier for the club to keep Mo Salah," he told the Daily Mirror.
"We know that Barcelona and Real Madrid will be in the market for the best players in the summer.
"And if you talk about the best players in the world right now, then Mo Salah must be included.
"I have seen the talk that Barca and Madrid are interested in him and we have seen in the past, with Suarez and Coutinho, how difficult it is for players to say 'no' when they get the chance to sign for one of those clubs.
"At this moment, though, I think Liverpool are a different club than what they were. Last year, they reached the Champions League final. This time, they challenged for the Premier League and (reached the) Champions League (final again).
"They are now a club with the potential to win the big trophies."
The former Spain international went on to say it would be difficult for Salah to turn the Spanish giants down should their interest in the former Chelsea star become more concrete.
"If Barcelona or Real Madrid come, you will be flattered. They are probably the only two teams that a Liverpool player would think about signing for," Garcia added.
"At this moment, Liverpool are also a club that gives you the chance to win trophies – and they will now want to take that final step.
"There is no doubt that Salah would be a star at Real Madrid or Barcelona because he has such fantastic quality.
"I have heard people compare him to (Lionel) Messi. For me, that is a little too much, but he does have that speed and skill and he could perform for any team in the world.
"In my opinion, he is just behind Messi and (Cristiano) Ronaldo – at the same level as (Eden) Hazard and (Raheem) Sterling."
