Klopp was unhappy with Marciniak throughout the game, believing he was unable to cope with the intimidation from the Spanish side that prompted the substitution of Sadio Mane at half-time before the forward was sent off.
The Reds boss was also shown a yellow card by the referee during the match, but later admitted: "I deserved it. I was just shouting in the direction, no bad words, I was not swearing,
"I was just unhappy with the overall performance and in that moment it finally came out and the ref didn’t like it too much.
