Chelsea defender Jose Bosingwa has apologised for his challenge on Yossi Benayoun.
Towards the end of Liverpool's 2-0 victory over Chelsea, the Israeli was wasting some time by shielding the ball near the corner flag.
Bosingwa then just kicked Benayoun in the back with a horrific challenge - he escaped punishment at the time as referee Mike Riley and his assistant, who was stood just a couple of feet away, took no action.
The Football Association is now waiting for Riley's report, amid calls for action to be taken against Bosingwa.
But the Portuguese man will hope to ease tensions and avoid punishment, after he offered his apology.
"I apologise for what I did and it was never my intention to hurt him," Bosingwa told the club's official website.
"I know it was wrong and I apologise."
