The Manchester City midfielder has enjoyed a fruitful campaign, scoring 11 goals and registering 20 assists in all competitions this term.
However, Salah has also been superb in 2017-18, netting a remarkable 40 goals and claiming 13 assists in just 45 appearances.
"I think if you can choose nobody from our team, I think he deserves it," De Bruyne told NBC Sports.
"Probably he's going to win it anyway. He's been remarkable and to compete with someone that's scored that many goals, you're not going to win.
"I'm very satisfied with my performance this year, with the team."
De Bruyne and Salah lead the nominations for the PFA award, with Man City's David Silva and Leroy Sane, Tottenham Hotspur striker Harry Kane and Manchester United goalkeeper David de Gea also shortlisted.
