Jurgen Klopp apologised to fourth official Neil Swarbrick after screaming 'nobody can beat us' in his face after Simon Mignolet's penalty save against Chelsea.
The Liverpool boss was left furious after referee Mark Clattenburg failed to award a free-kick for a foul on Dejan Lovren in the build-up to the visitors' spot-kick.
Diego Costa, who won the penalty after tangling with Joel Matip, saw his low effort well saved by Mignolet, but that wasn't enough to stop Klopp's furious outburst.
The former Borussia Dortmund manager was pictured angrily shouting in the face of Swarbrick on the touchline as the home fans at Anfield celebrated the stop.
