Atletico Madrid manager Diego Simeone admitted his behaviour was unjustifiable after he was sent off after a heated altercation with a Liverpool fan after the home side's stoppage time winner in the Champions League on Wednesday.
The Argentine had seen his side claw back a two-goal deficit but Virgil van Dijk then headed into the net in the 92nd minute to condemn Atletico to a 3-2 defeat at a raucous Anfield.
Simeone appeared enraged by a Liverpool fan behind the technical area and was eventually sent down the tunnel by Italian referee Maurizio Mariani.
