Vinicius Junior delivered a masterclass with a stunning hat trick as Champions League holders Real Madrid roared back from a two-goal deficit to thrash Borussia Dortmund 5-2 on Tuesday.
After a surprising slip against Lille in their last European outing, Madrid bounced back emphatically, dominating Dortmund in a repeat of last season's final with a blistering second-half performance.
Carlo Ancelotti’s men, who secured a record 15th Champions League title at Wembley, once again struggled early, with Donyell Malen and Jamie Gittens giving Dortmund a two-goal cushion before Madrid's unstoppable resurgence.
However, Antonio Rudiger and Vinicius pulled Madrid level with two goals in two minutes, and Lucas Vazquez fired home the third after 83 minutes.
Vinicius produced a brilliant solo goal for Madrid's fourth and slammed in the fifth as Los Blancos ended Dortmund's perfect start to the competition by producing yet another European comeback.
"We know that when we are at home, with our fans, anything can happen," Vinicius told Movistar.
"We went in (at halftime) very quiet and just listened to the coach; we said just one thing.
"If we scored the first, we would come back once again, and we made another comeback, thanks to the fans and the whole team who gave everything."
After midfield maestro Toni Kroos' retirement, and while trying to bed Kylian Mbappe into the team, Madrid has struggled to find balance and consistency this season.
They were frustrated for the first half-hour by the visitors, unable to create clear-cut openings before the game burst open.
"We have to learn from what we are capable of in this second half with high intensity and tempo; we have to start games like that, not wait until they’ve scored two to react like we did," warned Ancelotti.
"To be more balanced in terms of intensity between the first half and the second is something we have to achieve, and I am sure we will do it."
Malen opened the scoring with a cool finish after Julian Brandt won the ball back on the edge of the area, and Serhou Guirassy squeezed a pass through a tight gap to find the Dutch winger.
Four minutes later, Malen created the second, using his explosive pace to escape Ferland Mendy and crossing for Gittens to finish.
Madrid responded by carving open Dortmund before the break but without finding a killer finish.
Jude Bellingham, without a goal in 10 games this season, headed straight at Gregor Kobel when he ran onto a scooped pass into the area.
The England international, facing his former club, then struck the crossbar from close range on the rebound after teammate Rodrygo had also hit the woodwork, with Madrid fans barely able to believe they had not scored.
'We'll fight for everything'
The hosts turned the screw in the second half, and Kobel saved well at the near post from Vazquez but could not keep out Rudiger's powerful header from Mbappe's cross after an hour.
Two minutes later, Madrid was level when Mbappe was tackled in the area, but the ball fell invitingly for Vinicius to stroke home with ease.
Dortmund coach Nuri Sahin, formerly a Madrid player, took off goalscorers Gittens and Malen, but his team could not keep the insatiable hosts at bay.
Madrid's comeback was completed by Vazquez after Rodrygo did well to keep the ball from going out of play, and Vinicius added shine with his fine fourth.
The Brazilian, expected to claim his first Ballon d'Or on Monday in Paris, carried the ball forward without support and produced a lethal low finish.
Vinicius then added a fifth by bursting into the area and rifling past Kobel, also issuing a warning to La Liga leaders Barcelona, who visit the Bernabeu on Saturday.
"We'll go for it, in our stadium, with our fans, and we will fight for everything this season like always," added Vinicius.
