Barcelona, until recently one of the few clubs in world soccer whose players did not display a corporate logo, will switch to Qatar Airways as their official shirt sponsor next season, the Spanish club said yesterday.

The airline’s logo will replace Qatar Foundation on the front of their strip, the club said in a statement on their website. The change is part of a controversial sponsorship agreement signed with Qatar Sports Investment (QSI) last year.

Barca signed what was then the most lucrative shirt sponsorship deal in soccer, worth €30 million a year and helping to promote the Gulf nation.

As part of the deal with QSI, Qatar Foundation replaced the United Nations Children’s Fund (Unicef) on Barcas shirts, with the Unicef logo being relegated to the back.
