Florentino Perez: 'We'll bring in some brilliant players'
Real Madrid have had a difficult start to the transfer window, with Zidane stepping down as coach days after winning the Champions League.
Topgoalscorer and fan favourite Ronaldo then joined Juventus, and so far the club have only made a handful of young signings.
Los Blancos have been linked to Chelsea men Eden Hazard and Thibaut Courtois, but no deal has been made, or negotiations even started.
"We need to strengthen our present and our future. This is a great squad that will be strengthened by some brilliant players," Perez said at a news conference.
"We're in one of the richest periods of our history. We've won unique titles. We're sound institutionally, have strong financial power and have the supports of millions of fans."
"We're going to look to carry on winning and nobody should be in doubt about that. Many thought it was impossible to win three Champions Leagues in a row. We are Madrid and we always want more."
Despite winning the Champions League last season, the club finished third in La Liga after Barcelona and Atletico Madrid.
Ronaldo's exit was a blow for the club, and they will certainly be looking to bring in some replacements as soon as possible.
