On a terrible night for Arne Slot's team, who lost back-to-back games for the second time under the Dutchman, Galatasaray defeated Liverpool 1-0 thanks to a penalty kick in the first half from Victor Osimhen.

In addition to numerous missed opportunities and more defensive blunders at the back for Liverpool, Galatasaray won their first Champions League home game in seven years. Goalie Alisson and striker Hugo Ekitike also suffered injuries on the evening.

Arne Slot made a surprise selection with Mohamed Salah and Alexander Isak both named on the bench - with Jeremie Frimpong starting at right-wing - but what did not change was Liverpool's vulnerability at the back.

They were given a huge warning in the opening minutes when Baris Alper Yilmaz was played through on goal - with too much power and pace for right-back Dominik Szoboszlai. The forward forced a good save from Alisson Becker - before Liverpool missed a huge chance of their own.

Victor Osimhen's first-half penalty gave Galatasaray a 1-0 win over Liverpool on a disastrous night for Arne Slot's side, who suffered back-to-back losses for the second time under the Dutchman.

And 23 seconds later, Liverpool were made to pay. Yilmaz had the better of Szoboszlai again on the break and when the winger cut inside, Szoboszlai caught him with a flailing arm on the face. Referee Clement Turpin spotted it, allowing Osimhen to fire the spot-kick down the middle past Alisson.

Liverpool's response was better. Florian Wirtz forced a good save from Cakir while Milos Kerkez and Ibrahima Konate missed big close-range chances from separate corners.

Isak and Salah were brought on by Liverpool, and the latter shot directly at Cakir from an excellent position nearly immediately. Ekitike came off for Alexis Mac Allister after stretching for the ball and pulling up, severely halting the Reds' drive.

Before the Reds appeared to have a chance to rally when Konate was taken down by Wilfried Singo's challenge and referee Turpin signaled for a penalty, Conor Bradley sent a header wide of goal. Replays, however, demonstrated that Singo had the ball, and VAR appropriately intervened to nullify the penalty kick.

There would be no late drama this time for Slot's side, who have now hit a real bump in the road.
