Salah is the Premier League's top scorer with 29 goals.
De Bruyne has said that they aren't comparable as players, but admitted that Salah's record speaks for itself.
Manager Pep Guardiola's side have lost just once this campaign and hold a 16-point lead over second-placed United and De Bruyne believes that clinching the league title against their bitter rivals would add to City's joy.
Liverpool issued a public apology to City after the unsavoury scenes prior to the first leg of their Champions League quarter-final, which Jurgen Klopp's side won 3-0.
De Bruyne, however, thinks 38-goal Salah should win the accolade and says he voted for the Egyptian.
"The volume is always up", said De Bruyne, City's player of the season, who has driven their title challenge with ruthless brilliance throughout.
'I am very happy with myself, I am very pleased with how I have played, I didn't expect to be this good this season, to be honest'.
'I think it's just because it's the same manager, and it's both of us in the same season who are going well, that people are talking about it. "I think nobody expected it, but he hit the ground running".
All three spent a short time at Stamford Bridge before being sold on. That [at Chelsea] was an experience where I learned maybe the most out of how football goes.
"But I feel the best way to try to win is what we have done here since we've been together".
Liverpool were roared on by a raucous crowd at Anfield and De Bruyne hopes the tables will be turned by City supporters at the Etihad.
And it gives an insight into what other players may be thinking when it comes to the 36-goal attacker.
"Every time we get a player who hits the big heights everybody makes out that the likes of Real Madrid and PSG are looking at our players". "I don't look at what happened before, I wouldn't know how to choose anybody else, outside of Salah, if it's not our team".
