Real Madrid are in talks with Microsoft over the naming rights for their Santiago Bernabéu stadium.
Madrid president Florentino Pérez recently admitted the club was looking to secure a sponsor for one of European football's most revered stadia, and Microsoft confirmed they were in the running on Wednesday.
"We have an excellent relationship with Real Madrid and in fact we recently signed an agreement with its foundation," Microsoft's Spanish president Maria Garaña said.
"They've raised, as have other companies, renaming the stadium and we're only talking about this possibility."
The Bernabéu was renamed after Madrid's former chairman in 1955, having opened as Nuevo Estadio Chamartín in 1947, and holds around 85,000 spectators.
It is the third-largest stadium in Europe, behind only Wembley and Barcelona's Camp Nou, and has hosted four European Cup finals, most recently, Internazionale's 2010 triumph over Bayern Munich.
