Clubs in the UK must follow new rules when recruiting players from the European Union in the January transfer window as a consequence of Brexit.

Here, the PA news agency sets out how it will work.

Why are new rules needed?

Under-18s would now be barred from doing so, which means a move such as 17-year-old Jude Bellingham's from Birmingham to Borussia Dortmund in July could no longer happen. Over-18s would be subject to the rules applying to non-EU players in whichever EU country they were seeking to move to.
