Defending Bundesliga champions Bayern were in control from start to finish in a rematch of last season's German Cup final, with Olise in spectacular form despite the greasy conditions in the Bavarian capital.Dayot Upamecano headed the hosts in front from a corner and while Josha Vagnoman levelled things up for Stuttgart after the break, Bayern scored twice in three minutes through Olise and a Vagnomann own goal to restore control. Bundesliga debutant Ismael Saibari created a late goal for Aleksandar Pavlovic and Diaz scored in stoppage time to extend Bayern's unbeaten run in league openers to 15 seasons. "He relies heavily on intuition, reacting before the opponent does," Bayern defender Konrad Laimer said of Olise. "It's an incredible quality, especially in one-on-one situations. You need that instinct to read the situation: knowing when to pass, when to dribble, and when to shoot. "It's really fun to be out there on the pitch with him."With 14 goals including three hat-tricks, Harry Kane had scored against Stuttgart more than any other German opponent but had a quiet night and was subbed out late in the second-half. The big win will likely see Bayern top the table after matchday one, extending their streak to 67 matchdays dating back to September 2024. Bayern lost just one of 40 domestic matches last year but coach Vincent Kompany said it was his job to keep the squad hungry. "Everything starts again from zero. I hope all players are aware of that, but it's also my role to instill it into them."'Lights out' for Stuttgart
