Liverpool's challenge for the Champions League trophy will be white-knuckle until it finds a way to stabilize the back line.
Bayern Munich, Liverpool and Manchester City all prevailed, but Real Madrid lost to Shakhtar Donetsk Wednesday in the biggest upset of the new Champions League season so far.
Dortmund's Norway striker Erling Haaland kept up his prolific Champions League scoring form with a second-half goal to make it 2-1 but that was the German club's only consolation. Immobile, who played for Dortmund in the 2014-15 season, gave Lazio an early lead after their pressing secured the possession from the visitors' new signing Thomas Meunier.
Juventus made a winning start in the Champions League as they defeated Dynamo Kyiv 2-0 thanks to a pair of classic poacher's goals from Alvaro Morata in their Group G opener on Tuesday. Juve coach Andrea Pirlo enjoyed his first win as a manager in Europe's elite club competition, which he won twice with AC Milan during his playing days as a midfielder. With Cristiano Ronaldo ruled out following a positive test for COVID-19, Dejan Kulusevski was twinned with Morata up front and Federico Chiesa created some early chances for the visitors.
