Jordan Henderson's stunning strike ensured Liverpool came from behind to beat AC Milan once more with a pulsating 3-2 victory at Anfield to get their Champions League campaign off to a winning start.
The Reds famously came from 3-0 down to beat the Italian giants on penalties in the 2005 Champions League final in Istanbul but should have made far easier work of disposing of Stefano Pioli's men on their return to top-level European football.
Seven-time winners Milan were playing their first Champions League match for seven years and were given a rude awakening to the step-up in class but for a two-minute spell before half-time, that threatened to take the game away from Liverpool.
FikayoTomori's early own goal was scant reward for the home side's early dominance as Mike Maignan saved Mohamed Salah's penalty.
But goals from Ante Rebic and Brahim Diaz turned the game on its head completely against the run of play.
Salah levelled the scores once more before Henderson's thunderous finish proved a deserving winner 21 minutes from time. "It was a brilliant game," said Liverpool boss JurgenKlopp. "Very exciting, very entertaining with 10-15 minutes where we lost the plot."
A 0-0 draw between Atletico Madrid and Porto means Liverpool end the night on top of Group B and Klopp underlined the importance of a winning start in such a tough section.
