Angelozzi (Director of Football in Frosinone) today declared that Barrechenea convinced Kaio Jorge and Soulè to come to Frosinone, and then Kaio Jorge convinced Reinier to come too.
So this is the challenge that I propose: you can only buy players recommended by other players.
To do this, you must go to player interactions and click on recommend purchase, then select the role you need.
I don't want to put too many boundaries, just: you can only buy players recommended by other players, in any team.
Good luck!
