Wenger says it is RVP's United team-mate Michael Carrick, 31, who should be picking up the end-of-season PFA gong.
He said: "Robin stayed for a while without scoring. The vote happened during that period so that could go against him.
"Suarez has bitten into his reward! You also have Gareth Bale but I think Carrick is an under-rated player in England.
"Sometimes not only should the goalscorer be rewarded but the real players in the heart of the game. Carrick deserves it.
"I would choose Carrick as Robin had it last season. Give it to somebody different. He is a quality passer."
