Barcelona will be banned from signing players in January 2015 and the following summer.
Barcelona have had their appeal against their transfer ban rejected by FIFA.
The club were banned for two transfer windows from brining in any players to the club, but the ban was suspended for this summer's window whilst the appeal was being heard - meaning they were allowed to conduct transfer business normally.
The ban was down to the way the club signed player under the age of 18 from abroad, where they were found in breach of Article 19, which states:
"a) The player’s parents move to the country in which the new club is located for reasons not linked to football.
b) The transfer takes place within the territory of the European Union (EU) or European Economic Area (EEA) and the player is aged between 16 and 18. In this case, the new club must fulﬁ l the following minimum obligations:
i. It shall provide the player with an adequate football education and/or training in line with the highest national standards.
ii. It shall guarantee the player an academic and/or school and/or vocational education and/or training, in addition to his football education and/or training, which will allow the player to pursue a career other than football should he cease playing professional football.
iii. It shall make all necessary arrangements to ensure that the player is looked after in the best possible way (optimum living standards with a host family or in club accommodation, appointment of a mentor at the club, etc.).
iv. It shall, on registration of such a player, provide the relevant association with proof that it is complying with the aforementioned obligations.
c) The player lives no further than 50km from a national border and theclub with which the player wishes to be registered in the neighbouring association is also within 50km of that border. The maximum distance between the player’s domicile and the club’s headquarters shall be 100km. In such cases, the player must continue to live at home and the two associations concerned must give their explicit consent."
The delay of the ban has allowed Barcelona to have a busy summer in the transfer market, which has seen a number of high profile players arrive at the club as they begin life under new boss Luis Enrique.
Luis Suarez and Thomas Vermalen have been amongst those from the Premier League who have headed to the Nou Camp. Ivan Rakitic, Jeremy Mathieu, Claudio Bravo and Alen Halilovic have also been amongst their summer signings this summer.
Barcelona's ban will being in January 2015, and a statement on the FIFA website, read: "FC Barcelona is to serve a transfer ban which will see the club prevented from registering any players at both national and international level for two complete and consecutive transfer periods, starting with the next registration period (January 2015) given that the appeal of the club had been granted suspensive effect by the chairman of the FIFA Appeal Committee."
