European heavyweights Real Madrid and Manchester City both suffered big defeats in the Champions League.
Defending champion Madrid was humbled 3-1 at home by AC Milan, while Erling Haaland missed a penalty and City squandered a fourth-minute lead as it lost 4-1 at Sporting Lisbon, whose coach will soon take charge of its crosstown rival.
It was a much better evening for Liverpool, as Luis Diaz scored a hat trick and Cody Gakpo grabbed another goal in a 4-0 win over German champion Bayer Leverkusen at Anfield that marred Xabi Alonso's return to his old home.
The Leverkusen coach was given a warm welcome on his return to the club where he became a fan favorite as a player over five seasons between 2004-09. Alonso won the Champions League with Liverpool in 2005.
Liverpool moved top of the league phase table with four wins from four games, followed by Sporting and Monaco, both on 10 points after three wins and a draw. Under the new 36-team format introduced by UEFA this season, the top eight teams advance directly to the next round, and those from ninth to 24th enter playoffs to reach it, while the bottom 12 are eliminated.
Amorim's audition
Before their game, Sporting fans displayed a huge tifo thanking Rúben Amorim in his last home game before he takes over Manchester United.
Phil Foden then got City off to a flying start in the fourth minute, only the second goal Sporting has conceded in four games of the competition.
But Swedish forward Viktor Gyökeres scored a hat trick as Sporting came roaring back. Gyökeres first equalized in the 38th after a perfect through ball from Geovany Quenda, before Maximiliano Araújo made it 2-1 right after the break. Gyökeres then made it 3-1 from the penalty spot after Joško Gvardiol was penalized for a shove on Francisco Trincão in the area.
Haaland's penalty hit the crossbar, before Gyökeres showed the Norwegian how it's done with another spot kick at the other end to complete the scoring.
It is the first time since 2018 that City has lost three straight games, coming off a defeat to Tottenham in the English League Cup and a loss to Bournemouth in the Premier League.
“In my seven and a half years at the club, I don't remember losing three games in a row,” City midfielder Bernardo Silva said.
Madrid faltering
In Spain, Christian Pulisic sent in a corner for Malick Thiaw to head Milan into a 12th-minute lead, ensuring Madrid trailed in a third straight game in the Champions League this season. The 15-time champion had already lost to surprise team Lille in their second game.
Vinícius Júnior equalized from the penalty spot in the 23rd after he'd been tripped, but Álvaro Morata pounced on the rebound after Andriy Lunin saved Rafael Leão's shot to restore the visitors' lead against his former club.
Morata had already been given a hostile reception from the home fans, who evidently remember the goal he scored to take Juventus through to the 2015 final at their team's expense.
Tijjani Reijnders scored Milan's third goal as the home fans made their frustrations known at Santiago Bernabéu Stadium.
“The last two defeats are inexplicable. We have to analyze and react quickly," Lunin said, referring to Madrid's 4-0 loss to Barcelona in its previous Spanish league game.
It's the first time since 2009 that Madrid has lost two successive games at home with at least three goals conceded in each, according to Opta.
“We have to get back on track,” Lunin said.
Other results
German forward Nicolas Kühn scored twice as Celtic defeated Leipzig 3-1 at home, and Juventus drew 1-1 at Lille.
Lille midfielder Edon Zhegrova eluded two defenders before playing a perfect pass for Jonathan David, who fired inside the far post, but Dušan Vlahovic equalized with a penalty for the Italian club.
Donyell Malen scored late for Borussia Dortmund to beat Sturm Graz 1-0 at home, and Thilo Kehrer did likewise for Monaco to win at Bologna 1-0.
United States midfielder Malik Tillman scored one goal and set up another as PSV Eindhoven beat Spanish team Girona 4-0.
