Italy’s bid to overturn a first-leg deficit in the UEFA Nations League quarterfinals suffered a major blow as defender Riccardo Calafiori has been ruled out of the crucial second leg against Germany. The 22-year-old sustained a knee injury late in Italy’s 2-1 loss at San Siro, prompting his withdrawal from the squad. The Italian Football Federation (FIGC) confirmed that Calafiori will return to Arsenal for rehabilitation. With forward Mateo Retegui already sidelined, Italy travels to Dortmund undermanned and under pressure.
