Barca announce shirt sponsorship deal
Barcelona have confirmed a shirt sponsorship deal with Qatar Foundation worth €30 million a season until 2016.
It will not affect the existing deal with Unicef, whereby Barca pay the international children's charity to carry its logo.
The agreement - which marks the first paid sponsor in Barca's history - will help to alleviate debts which, in July, stood at €442 million. The club lost €77 million last season.
They will earn €165 million across the course of the deal, with €15 million to be paid for the remainder of this season. It is said to be the biggest such deal in the history of football, with Manchester United and Liverpool - the nearest rivals - earning €23.6 million from their deals with AON and Standard Chartered this season.
Confirming the agreement at a press conference at Camp Nou on Friday, vice-president of finance Javier Faus said: "With this agreement, the FC Barcelona brand becomes the undisputed leader in football, ahead of its international competitors."
Dicussions over the placement of the Qatar Foundation logo will be held, but Unicef will retain priority placing.
The Qatar Foundation, founded in 1995, has set up projects focusing on education, scientific research and community development.
