“In general, there will not be big transfers this summer," he told
El Larguero. "When money does not flow from the rich clubs to the poor clubs, everyone suffers.
"It's impossible to make signings like Mbappe and Haaland, in general, not just for Real Madrid, without the Super League.
“If we don't sign Mbappe this summer, I don't think any fan will shoot himself in the head. They know we're doing our best, and if things don't happen, it's because they're impossible.”
Perez also discussed the future of Sergio Ramos, whose contract at the Santiago Bernabeu expires in just over two months.
The Madrid president described the Spain international as “like a son” but he admitted the club could be forced to cut costs in the summer.
“It depends on Real Madrid's situation," he said when asked if Ramos was likely to sign a new deal.
"This year we're bringing in €300 million less. We need to sell a player, do things.
"I've done what I can up to now and I haven't done it badly. Despite a few people saying I don't know about football.
“ I know what it's like to come into a club in 2000 where people hadn't been paid. I put up everything I could and changed the world with the Galacticos and went from losing €30 or 40 million a year to bringing that in."
