No matter what you try, it is impossible to schedule friendlies between International B teams. This gives the International B team what is effectively zero purpose outside of use by visitor nations to Copa America and African Nations for the CHAN Cup. I propose two features in order to revatilse the inter nal B team in FM25. These are:
Feature 1:
Application to join Copa America.
Each time Copa America is held, the B teams of two random nations are selected as 'guests' to take part in the tournement. Instead of these being random, International Manger Players could be sent an invite to take part in the tournment (players are automatically chosen to take one of the spots if they choose yes).
Feature 2:
Allow International B Team Friendlies.
In the current version of the game, as you can see bellow, it is impossible, no matter what, to organise a B team friendly. Although this is somewhat realistic as B Teams are now mostly inactive, it would be a useful asset to try out players without having to call them up to the main team. Additionally B teams of large nations could play against smaller national teams to give players international experience.
