European heavyweights Real Madrid and Manchester City both suffered heavy defeats in the Champions League on Tuesday.

Defending champions Madrid were humiliated 3-1 at home by AC Milan, while Erling Haaland missed a penalty and City squandered a fourth-minute lead by losing 4-1 at Sporting Lisbon, whose coach will soon take charge of its crosstown rival.

It was a much better night for Liverpool, as Luis Diaz scored a hat-trick and Cody Gakpo scored another goal in a 4-0 win over German champions Bayer Leverkusen at Anfield that spoiled Xabi Alonso’s return in his old house.

The Leverkusen manager was warmly welcomed on his return to the club where he became a fan favorite as a player for five seasons between 2004 and 2009. Alonso won the Champions League with Liverpool in 2005.

Before their match, Sporting fans displayed a huge tifo to thank Rúben Amorim in his final home game before he takes the reins at Manchester United.

Phil Foden then got City off to a good start in the fourth minute, only the second goal Sporting have conceded in four games in the competition.

But Swedish striker Viktor Gyökeres scored a hat-trick as Sporting came roaring back. Gyökeres first equalized in the 38th after a perfect pass from Geovany Quenda, before Maximiliano Araújo made it 2-1 just after the break. made it 3-1 in the 49th minute from the penalty spot after Joško Gvardiol was penalized for a push on Francisco Trincão in the box.

Haaland’s penalty hit the crossbar, before Gyökeres showed the Norwegian how to do it with another kick at the other end to complete the score.

In Madrid, Christian Pulisic sent a corner to Malick Thiaw to give Milan the lead in the 12th minute, securing Madrid’s third consecutive Champions League appearance this season.

Vinícius Júnior equalized from the penalty spot in the 23rd after being 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 received a hostile reception from the home fans, who obviously remember the goal he scored to take Juventus to the 2015 final at his team’s expense.

Tijjani Reijnders scored Milan’s third goal as the home fans made their frustration known at the Santiago Bernabéu stadium.

Additionally, German striker Nicolas Kühn scored twice as Celtic beat Leipzig 3-1 at home and Juventus drew 1-1 at Lille.

Lille midfielder Edon Zhegrova evaded two defenders before making a perfect pass to Jonathan David, who shot at the far post, but Dušan Vlahović equalized from the penalty spot for the Italian club.

Donyell Malen scored late as Borussia Dortmund beat Sturm Graz 1-0 at home, and Thilo Kehrer did the same as Monaco won at Bologna 1-0.

American midfielder Malik Tillman scored one goal and set up another as PSV Eindhoven beat Spanish side Girona 4-0.
