Or easier, who knows. We could have a points system on immigration, and favour anyone who is a "professional footballer".
Or harder, where, as was being seriously debated a few years back, the FA introduce tighter regulations on the number of foreigners in each team or squad. At the time we were restricted by what we could do (I believe) due to the EU Freedom to Work Regulations.
But post-Brexit it's presumably entirely up to us. Whether that's a good thing, looking at the cretins we currently have in Westminster, well, that's to be seen.
The FA want to increase the HGP number and only allow 13 overseas players.
The PL obviously rejected this, as I understand when we need to get work permits for players the FA have to sign it off, I can’t see them doing this without the PL budging on HGPs.
