The Argentine, who made the final three for the award but ultimately missed out to Robert Lewandowski, reunited with former Barcelona teammate Neymar at the Parc des Princes following his summer exit from Camp Nou.
Messi is afforded a vote in the awards due to his position as Argentina captain, and he selected Neymar as his first choice, which is worth five points to the overall standings.
Neymar made 33 appearances for PSG over the course of 2021, scoring 11 goals and creating nine more - figures far below those posted by the likes of Lewandowski and fellow finalist Mohamed Salah.
However, the world's most expensive footballer did also help Brazil to the final of the Copa America, scoring six goals and assisting nine more in just 13 appearances for his country throughout the calendar year.
The 34-year-old also selected Argentina boss Lionel Scaloni as his coach of the year, followed by Italy boss Roberto Mancini and Manchester City manager Pep Guardiola, ignoring current club boss Mauricio Pochettino.
