Floriana signed Malta Under-21 international attacking midfielder Jan Busuttil from Pietà Hotspurs.
A product of Pietà, Busuttil made his Premier League debut last season.
He is the third local player to join the Greens after Brandon Paiber who made his move a permanent one and Ryan Camenzuli.
Floriana had earlier secured the services of Matias Nicolas Garcia, Francisco Diego Venancio da Silva, Tiago Adan Fonseca and Augusto René Cáseres.
