Presidential elections are being held ahead of schedule after the incumbent Josep Maria Bartomeu resigned in the midst of a bitter public dispute with Messi.
The Argentine's future at Barca is still to be resolved, with his contract set to expire at the end of the season and a number of clubs reportedly interest.
However, one of the men who could succeed Bartomeu has made a huge election promise that could convince Messi to stay put.
Outlining his plans, Rousaud told Marca: "We will hold a referendum to change the name of the stadium to Camp Nou - Leo Messi."
Messi is Barcelona's most decorated player (34 trophies) and the club's all-time top goalscorer (640 goals).
He is also likely to surpass Xavi's record for all-time appearances (767) before the season is out, needing to play just 26 more games.
