"The analysis of these new samples in the laboratory has determined that our coach, Diego Pablo Simeone, has given a positive result for COVID-19. Fortunately, he does not present any symptoms and is isolating at his home and fulfilling the quarantine after taking training with the team since last Monday," it added.
