Lorenzo Sanz, who, as its president, helped return the Spanish soccer club Real Madrid to victory in Europe’s top competition after more than three decades, died on Saturday in Madrid. He was 76.

His family said he died after contracting the coronavirus.

Mr. Sanz had tested positive for the virus after entering a Madrid hospital on Tuesday with a fever. He also had kidney failure, according to local news media reports.

His son Fernando said that Mr. Sanz had tried to fight the fever at home for eight days before going to the hospital because he did not want to burden an already strained Spanish health-care system.
