“Lionel Messi set up goals for Alexis Sánchez and Cesc Fábregas in Barcelona’s 2-0 Champions League Group G victory over Benfica on Tuesday but their victory was overshadowed by a serious-looking arm injury sustained by their captain, Carles Puyol. The Catalans had Sergio Busquets dismissed two minutes from time but will be more concerned about Puyol, who landed awkwardly after leaping for a ball and was carried off on a stretcher in obvious pain on 78 minutes. The Spain international was playing his first match since recovering from a knee problem. The club said later he had dislocated his elbow.” Guardian
