Harry Kane produced a remarkable four-goal haul to make English history as Bayern Munich demolished visitors Dinamo Zagreb 9-2 in their record-breaking Champions League opener.
Kane, who scored a hat-trick in their Bundesliga win over Holstein Kiel on Saturday, converted a 19th-minute penalty before goals from Raphael Guerreiro and Michael Olise in the first half on Tuesday.
Bruno Petkovic and Takuya Ogiwara led a fightback early in the second half, with Dinamo hoping to find a way back, but Bayern responded through goals from Kane and Olise.
Kane netted his third and fourth with penalties shortly after, helping him onto 33 strikes in the competition and comfortably past Wayne Rooney's 30-goal record among English players in the Champions League.
Leroy Sane added another in the 85th before fellow substitute Leon Goretzka headed in the hosts' record-breaking ninth finish, the most by one team in a single match since the Champions League was introduced.
Data Debrief: Penalty perfection for Kane
Deadly finisher Kane accumulated 3.76 expected goals (xG) of Bayern's total 6.27 tally for the match, with the 31-year-old finding the target with six of his eight attempts in what proved to be a total domination.
Kane is the first player to score a hat-trick of penalties in a European Cup/Champions League match, and the first Englishman to score four in a match in the competition since Alan Smith for Arsenal against FK Austria Wien in 1991.
There was history elsewhere, however, as Thomas Muller appeared in his 152nd Champions League match for Bayern, breaking Xavi's record for the most matches with one club in the competition (151 for Barcelona).
Vincent Kompany will be looking forward to the rest of this European term, too, after Bayern started a 21st straight campaign in the competition with victory, with their last such defeat coming against Deportivo de La Coruna back in 2002-03.
