Salah has been in an imperious form all through the season, scoring 44 goals in 51 appearances in his debut campaign with the Anfield outfit.
The Egypt international has forged a good partnership with Firmino and Sadio Mane with the three contributing a huge chunk of the goals scored by Jurgen Klopp’s side this season.
The Brazil forward has notched 27 goals across all competitions this season, including 11 in the competition.
And Ramos, who is hoping the Spanish giants lift their third consecutive Champions League trophy, has hinted on how they plan stopping the deadly duo.
“We know they're very tough opponents. They are very fast going forward and can really hurt you on the break,” Ramos told Uefa website.
“[Roberto] Firmino and [Mohamed] Salah are such quick and direct players who are very difficult to get hold of, so we'll try to keep them under control and ensure they don't have one of their inspired days, because they can certainly cause you damage.
"[Liverpool are] very good technically and are full of pace, but we'll try to hurt them with our players who have similar attributes.
“We know we can also cause them problems on the counter. We'll try to take advantage of that and we also know we are a threat from set pieces.”
