Defying ban, Barcelona signs Sevilla's Aleix Vidal

Fifa rules state that international transfers are only permitted for players over the age of 18 - unless the player in question meets one of three qualifying criteria.

Vidal is set to replace Dani Alves at right-back, with the Brazilian out of contract. Vidal, who is signed for a five-year deal, will, however not be able to play till January 2016.
