British football could be radically changed if the UK votes to leave the European Union, according to experts and leading voices in the game.
Some fear so-called Brexit could lead to more than 100 Premier League stars losing the right to play there, others say it may give home talent a chance.
The UK will decide if it wants to stay in the EU in a referendum on 23 June.
“Leaving the EU will have a much bigger effect on football than people think,” said football agent Rachel Anderson.
“We’re talking about half of the Premier League needing work permits.
“The short-term impact would be huge but you could argue it will help in the long term as it could force clubs to concentrate on home-grown talent.”
Players with an EU passport are currently free to play in Britain, but those without must meet Home Office criteria, the most important being they are established internationals for leading nations.
An analysis of squads in the first two tiers in England and the Scottish Premiership has revealed a total of 332 players would fail to meet the current standards.
Aston Villa, Newcastle United and Watford could lose 11 players from their squads, while Charlton Athletic would need to find 13 replacements.
