Atletico Madrid manager Diego Simeone admitted his behaviour was unjustifiable after he was sent off following a heated altercation with a Liverpool fan following 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.
