Britain's decision to quit the European Union has sent shockwaves across the globe and the sporting world now also faces an uncertain future.
Although the impact will not be immediate and is still to be fully worked out, European players are likely to find it much harder to join British clubs.
Currently, players with an EU passport can move freely between member states but with the UK now leaving, European stars would be subject to the same strict conditions as athletes from outside of the continent.
It's now likely that European players will have to obtain work permits to move to the UK, which is heavily dependant on what they can contribute to Britain.
Under current employment rules, non-EU players from a nation ranked in the top ten of the FIFA rankings need to have played in 30% of their country's international games in the two years prior to their application to be considered for a permit to work in the UK.
That figure rises to 45% for a team ranked between 11-20 and keeps climbing the further down the rankings you go.
It's not thought that European players currently playing in the UK will be affected by the Brexit, but obviously getting players over here in the future could be a lot more difficult.
A number of Norwich City players wouldn't have been able to join the club last season if Britain hadn't been in the EU when they joined, including January recruit Ivo Pinto.
Current Norwich City players who wouldn't have been able to join the club
- Vadis Odjidja-Ofoe (Belgium)
- Ivo Pinto (Portugal)
- Martin Olsson (Sweden)
- Tony Andreu (France)
The likes of Jonas Knudsen and Bartosz Bialkowski would also have struggled to sign for Ipswich Town had things been different.
Another implication of the vote is that British clubs will now not be able to sign European players under the age of 18 for their academies, meaning that clubs are likely to shift their attention to producing more homegrown talent.
