Liverpool’s Mohamed Salah netted a double, including the winner, as the Reds secured a 3-2 victory over Atletico Madrid in a thrilling Champions League tie.
Atletico forward Antoine Griezmann also scored twice in Madrid but was given a straight red card for a high boot into Roberto Firmino’s face.
Salah fired home the winner from the spot after Griezmann had seen red, but the action was not over in a compelling encounter, with Atletico awarded a penalty of their own, before VAR intervened to overturn it.
The win kept Liverpool top in Group B on nine points, five ahead of second-placed Atletico and Porto in third, with AC Milan pointless at the foot of the table.
Salah opened the scoring with a deflected effort in the eighth minute and Naby Keita added a second with a thunderous volley five minutes later as Liverpool looked set to crush Diego Simeone’s side.
However, Liverpool’s defence imploded shortly afterwards and Atletico came roaring back, with Griezmann at the centre of the action.
First he steered home a Koke shot in the 20th minute to reduce the deficit.
Fourteen minutes later he drew his side level, a superb first touch opening up the space in front of him for a clinical finish low past Alisson’s left hand.
After a frenetic opening 45 minutes, Liverpool finished the first half on the ropes, but a reprieve was not long coming as the second period got underway.
Yannick Carrasco forced an early save from Alisson but then Griezmann was sent off seven minutes after the break for carelessly planting his foot in the face of Firmino as he challenged for a high ball.
Simeone’s reaction was to keep urging the home crowd on, and his team looked capable of hanging on with 10 men until another costly lapse.
Defender Mario Hermoso conceded a penalty by barging into Diogo Jota, and Salah made no mistake from the spot to put Liverpool back in the lead.
However, Liverpool seemingly tripped themselves up again when Atletico Madrid were awarded a penalty after Jota appeared to bundle over Jose Maria Gimenez — only for the decision to be overturned after a lengthy VAR review.
Former Liverpool striker Luis Suarez flashed a stoppage-time shot over the bar before being booked for an angry exchange with the referee as he sought to find an equaliser for his side.
With seven minutes of stoppage time added on, Liverpool were left hanging on, but they managed to see the game out.
