Microsoft have confirmed they are in talks with Real Madrid over a naming rights deal for the Santiago Bernabeu.
Real Madrid are looking to raise €400 million in order to finance works to the Bernabeu which would increase the capacity of the stadium from 80,300.
Real Madrid president Florentino Perez confirmed last month that renaming the Bernabeu was an option being explored.
"We are working on a sponsor," he said. "We are on with it. At best the stadium will have a name added to it if we can find one.”
Now, head of Microsoft's Spanish division Maria Garana confirmed there has been some discussion over a potential naming rights deal.
“We are talking,” Maria Garana told Antena 3.
“We have an excellent relationship with Real Madrid and in fact recently we signed an agreement with its [charity, Real Madrid] foundation.
“They have proposed to us, and to other companies, renaming the stadium, but we are only talking about this possibility.”
Emirates, who own the naming rights to Arsenal's stadium, have also reportedly been in talks with Real Madrid.
The Dubai-based firm paid £150 million to the Gunners to be their lead shirt sponsor until 2015 and to continue sponsoring the stadium until 2028.
If confirmed, the Microsoft deal could become the largest of its kind in the world.
