Liverpool threw away a two-goal lead as Monaco came from behind to win 3-2 in a pre-season friendly at Anfield on Sunday in Andoni Iraola's first game in charge on home soil.
Andoni Iraola had watched his side start brightly in front of their own supporters, but defensive lapses either side of half-time allowed the Ligue 1 visitors to grow into the contest.
Alexander Isak opened the scoring in the 16th minute when he latched onto Ryan Gravenberch's pass and finished calmly to put Liverpool ahead and give the new Anfield crowd an early lift.
Florian Wirtz doubled the lead in the 29th minute after combining with Isak, firing home to make it 2-0 and cap a dominant opening half hour for the hosts.
Monaco responded before the break when Aleksandr Golovin converted a 44th-minute penalty to halve the deficit and shift momentum heading into half-time after Liverpool were penalised inside their own area.
Mika Biereth brought the visitors level in the 56th minute with a composed finish that punished Liverpool's slack defending at the start of the second half.
Paris Brunner completed the turnaround in the 88th minute when he headed in the late winner after meeting a cross from close range to stun Anfield.
The afternoon also saw Victor Munoz make his first appearance for Liverpool, with the youngster introduced as Iraola continued to rotate his squad in pre-season.
Liverpool had looked in control after their fast start but ultimately paid for conceding cheap goals, while Monaco showed clinical edge to overturn the deficit late on.
For Iraola, the defeat in his first Anfield outing offered a sobering early lesson, even as Isak and Wirtz provided encouraging signs in attack before the collapse.
