Following the General Election, the UK now look set to leave the customs union under a Conservative government - and here’s what it come mean for the Whites and fellow clubs throughout the EFL:
Brexit will naturally affect transfers, especially when it comes to Marcelo Bielsa trying to sign players from overseas.
Without free movement, EU nationals will now require a work permit to play in England - while previous rule caveat to the transfer rules which govern 16 to 18-year-olds and allowed them to switch between nations in the EU will be rendered defunct for teams in England.
That means Leeds won’t be able to recruit youngsters from overseas as easily have they done in the past, and may focus clubs’ minds on developing local talent.
PREMIER LEAGUE EFFECT
Top flight clubs are also set to find there are extra hurdles in their way when it comes to bringing in players - which could, in turn, see them turn to lower league clubs to bring in domestic youngsters rather than overseas equivalents.
Leeds, who could indeed be a Premier League club next season, have already seen their some of their youngsters pillaged by top flight clubs in recent years, and that may only increase after Brexit.
This has been a concern for many clubs - and one which Burnley chairman Mike Garlick believes may come to fruition.
In an interview with the BBC, he suggested that Brexit could ‘threaten to make the widening inequality gap in our top division even worse’, meaning the chances of a club breaking into the top six could become even slimmer.
COULD THERE BE POSITIVES?
Former Cardiff boss Neil Warnock, however, feels Brexit could have some positive implications for teams in England.
"I can’t wait to get out of it if I’m honest,” he said.
“I think we’ll be far better out of the bloody thing. In every aspect.
"Football-wise as well, absolutely. To hell with the rest of the world.”
