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