Speaking at a sponsor's presentation, Perez admits defending their Champions League crown was a priority.
"Like La Décima obliges us to look towards La Undécima, we also want to achieve the best club in the 21st century, as we did in the 20th century," said Perez.
"This is a strategic deal to help the club aspire to this. ...the commercial arrangements will enable Real Madrid to meet one of its most fundamental future challenges, to convert the Santiago Bernabéu into the best sporting venue in the world."
