Bayern Munich became the first team to score nine goals in a game in the modern Champions League as the new format of Europe's elite club competition kicked off on Tuesday, with title holders Real Madrid and Liverpool also among the winners.

Harry Kane scored four goals, including three penalties, as Vincent Kompany's Bayern hammered Croatian champions Dinamo Zagreb 9-2 at the Allianz Arena.

Michael Olise scored twice on his Champions League debut, while Raphael Guerreiro, Leroy Sane and Leon Goretzka were also on target for the home team in Germany.

Dinamo were 3-0 down at the break but scored twice in two minutes just after half-time to give the hosts a scare, with Bruno Petkovic and Takuya Ogiwara on target. But Bayern then scored six times from the 57th minute onwards.
