Gary Cahill has launched a tirade against Corinthians striker Emerson after the defender was sent off for retaliating to a challenge during Chelsea's Club World Cup defeat on Sunday.
Cahill, 26, was infuriated after being given his marching orders in the 89th minute and he believes the initial outburst from Emerson was just as worthy of a red card.
"It was a bad reaction from me," Cahill said. "I tackled him, we tangled up, he lashed out with his arm and hit me in the face. I thought that was out of order but I reacted in a bad way.
"I am angry about it. I'm disappointed in myself for my reaction but also because it's ok for someone to lash out at you but you do something back and it's deemed a red card."
Cahill launched himself into the diving debate, taking responsibility for his own actions but insisting there was not enough malice in his kick for the Brazilian to get injured.
"It probably is a red card but the reaction of the guy is totally out of order for what I did," he said. "If you see the impact it wouldn't have been enough to knock over my one-year-old daughter. I'm still angry.
"There are two different stories. Someone's smashed me in the face but I didn't roll around on the floor for five minutes holding my head up. I got up, reacted and tapped him in the shin. He felt the need to go down, roll around on the floor about five times holding his face. I suppose that's the story of the game really."
Cahill will be suspended for Chelsea's Capital One Cup clash with Leeds on Wednesday, with FIFA set to decide whether that ban shoulkd extend to Sunday's Premier League match against Aston Villa.
