**Liverpool Triumphs Over Leverkusen with Stellar Second-Half Performance**

In a memorable Champions League encounter, Liverpool gave their former player Xabi Alonso a tough homecoming as they overwhelmed Bayer Leverkusen with an emphatic second-half display at Anfield. The reigning German champions, who had come into the match unbeaten, were dealt a heavy 4-0 defeat. Liverpool's relentless attack was led by a hat-trick from Luis Diaz and a decisive header by Cody Gakpo, securing their perfect record in the competition so far.

Arne Slot's Liverpool side showcased exceptional form, taking control of the game after a more balanced first half. Despite a respectful reception for Alonso, who now manages Leverkusen, the home team showed no mercy on the pitch. The former Liverpool midfielder, who had said before the match that he wasn't in town for sentimental reasons but to win, faced a harsh reality as his team struggled to keep up with the Reds’ pace and precision.

The first half saw moments of promise from both sides, but few clear chances. Liverpool's initial threat came from a combination between Luis Diaz and Cody Gakpo, though Gakpo’s shot was deflected. Leverkusen, with players like Granit Xhaka and Florian Wirtz, managed to navigate through Liverpool’s midfield but lacked the finishing touch. Jeremie Frimpong had a penalty appeal waved away after going down under slight contact from Virgil van Dijk, and a disallowed goal for handball kept the score level at half-time.

The shift in momentum began with an excellent chipped goal by Diaz, following persistent efforts from Curtis Jones. This first breakthrough dismantled Leverkusen's defensive efforts, and seconds later, Salah and Diaz partnered to set up Gakpo for a header that, after a VAR review, was confirmed as Liverpool's second goal. Leverkusen's Victor Boniface squandered a prime opportunity to claw back into the game, heading wide from a promising cross.

Liverpool’s dominance continued as Salah's floated cross found Diaz again, who coolly slotted the ball into the net for his second. Diaz completed his hat-trick with a rebound off Darwin Núñez’s effort, sealing a comprehensive 4-0 victory. The Kop, in high spirits, even took a moment to serenade Alonso, appreciating his history with the club despite the night’s result.

This victory propels Liverpool to the top of their Champions League group, confidently advancing with 14 wins out of their first 16 games under Slot. For Leverkusen and their manager, it's back to the drawing board after a chastening evening at Anfield.
