An 88th-minute Davide Frattesi goal took Inter Milan to a 2-1 win at Bayern Munich on Tuesday, giving the Italians the edge after the first leg of their Champions League quarter-final. Undermanned Bayern, nursing a bulging casualty ward, set the tone in the first half-hour, with Michael Olise and Harry Kane narrowly failing to break through. Inter opened the scoring on the 38-minute mark when Marcus Thuram's clever back-heel found Lautaro Martinez who blasted home. The Italians maintained control until Bayern veteran Thomas Mueller, days after announcing a summer departure after 25 years at the club, scored the equaliser with a typical poacher's finish with five minutes remaining.
