Liverpool's Salah pipped De Bruyne to the prestigious individual award earlier this month following a scintillating campaign that has seen him score a record-equalling 31 goals in the Premier League and 43 across all competitions.
De Bruyne had been the favourite earlier in the campaign having established himself as the standout player in a Manchester City side which cantered to the Premier League title, and Neville confirmed that his vote would have gone the Belgian's way.
"If I was still a voting member I would have personally given the PFA Player of Year to Manchester City's Kevin De Bruyne. That's not because I believe it has to go to the league winners or that Mo Salah doesn't deserve it," Neville told Sky Sports News.
"Salah has impressed more people in the game, that's a matter of fact. In a democracy the players who have played against him have voted for him. I can't disagree with giving it to Salah, who has achieved above and beyond what we expected from him this season.
"However, I would have edged to De Bruyne because his performances have been like artwork and, in terms of his assists and controlling football matches, he has just been magical to watch. We heap praise on certain players and I have not got one negative word to say about him.
"The work he does off the ball is unbelievable, although I certainly wouldn't have enjoyed playing against Salah."
Salah needs just one more goal to become the highest-scoring player in a 38-game season in Premier League history.
