Hey Paul,
I took a look at the unlicensed national teams, the European leagues you have created, Bundesliga and Championship, and the five created teams of the other European teams.
Here are many players, whom you could add a commentary name using English commentators:
NATIONAL TEAMS:
Croatia: Vida (commentary: Vidal, you cannot hear the L)
Montenegro: Novakovic
Slovakia: Cech
Burkina Faso: Diakité, Koné
Guinea: Pogba (2x), Bangoura, Camara (2x)
Mali: Diakité (2x)
Senegal: Mané (2x), Sané
Costa Rica: Miller, Calvo
Honduras: Chavez (2x), Bengtson
Jamaika: Miller, Powell, Taylor
Mexico: Rodriguez, Aguilar
Panama: Rodriguez, Gomez (commentary: Gomes), Sanchez
USA: Jones
Ecuador: Dominguez, Mendez
Paraguay: Oviedo, Barreto, Silva, Aguilar, V.Caceres, Ortiz
Venezuela: Vega, Morales
Uzbekistan: Izmailov, Denisov

That's all I have found.
There should be more players at the Mexican league because of their Spanish names (Rodriguez, Morales, Chavez, Sanchez, Gomez,...) but I renounced to check them. I think there are too many...
