The renovation team utilises Roman techniques with raising the top, so as not to affect the operation of the stadium during the football season. "The project is complex because it will not stop the football and therefore complicates the works and design, which has a roof that encloses the whole stadium. They are going to lift the roof like the Romans did, but with modern technology. They will raise the inner ring by string-pulling with hydraulic jacks, bridge technology and ski lifts in a short period of time in the summer to respect the sporting calendar," said Tristán López Chicheri, the individual in charge of the renovation. In March 2020, Real Madrid decided to expedite the renovations after the Royal Spanish Football Federation suspended La Liga due to the COVID-19 pandemic. The expedition included interior work, which made the pitch unplayable and prompted Real Madrid to play their matches at the Alfredo Di Stéfano Stadium instead.
