The talented 21-year-old midfielder has attracted great interest this summer, but Benfica have been slow to accept any offers.
But a season-long loan move to Monaco is ‘very close’ to being finalised, according to A BOLA.
Monaco will pay a €2m loan fee for Florentino, but will not have an option to buy.
At the end of the season, Florentino will either return to Benfica or be sold.
While in France, Florentino will have a higher salary than what he earns at Benfica, all of which will be paid by Monaco.
Florentino has made 69 first-team appearances for Benfica after coming through their academy system.
