As I understand it there are two parts to footballers qualifying for a visa/work permit, a good amount of recent international representation and the status of the league they are coming from. He doesn't have the required international minutes. It seems a cut and dried situation. It's not like appealing a red card which could be open to interpretation.The pre brexit world has the uk work permit office determined to keep players out.
The new world means its a free for all to give a nod and an envelope and anyone seems to be able to get a permit as a footballer.
Somethings changed in the rules on permits for sure.
