It's fair to say Liverpool fans were not happy with Michael Oliver after the referee awarded Arsenal a controversial penalty and a chance to go 3-2 up.
The Reds had twice fought back from going behind at the Emirates Stadium. Darwin Nunez tucked home a tempting Luis Diaz cross to cancel out Gabriel Martinelli's early opener, but Jurgen Klopp's side went into the break 2-1 down after Bukayo Saka slid home five minutes into injury-time before Roberto Firmino levelled again in the second half.
Liverpool's resilience was duly tested as Luis Diaz and Trent Alexander-Arnold were both forced off with injuries, and Oliver's decision not to award a spot-kick in the first-half for Gabriel's suspected handball could easily have gone the other way. The away end will have felt even more hard done by then after the tiniest contact from Thiago sent Gabriel Jesus flailing and persuaded the referee to award Arsenal a penalty.

Jordan Henderson led the protests, but almost looked in a state of shock that the foul was given before a coming together with Granit Xhaka. There was a long delay as Saka weighed up his options, but the Arsenal winger remained calm and emphatically fired into Alisson's bottom corner.
And Reds fans were far from happy at the decision.
