Brexit: new immigration rules for football players – are you ready for the January transfer window? - Walker Morris
The UK's new immigration system will fundamentally impact the way in which clubs can engage football players from Europe & beyond, from 31 December 2020.www.walkermorris.co.uk
Potentially, though I don't think it'll affect loans as much (that would probably be the case with the other clubs the prince has, similar to coulibaly) as it'd be under a "T5 temp sports player" also, it looks like it's under review for the summer window, so hopefully they'll change the rules a bit.
TBH, I'm no fan of Brexit. But this is something I'm quite happy with as a result. If it gives young English players and managers more opportunities, then I'd be happy to see how the rules go for a few years
