Nevertheless, the former Arsenal and Manchester City stalwart insists that he will bounce back from the mistake by learning from the experience.
"It was a terrible pass by me," he told The Liverpool Echo. "You have to make the right decisions and I took a bad decision.
"I made a very bad pass. I don't know why I passed the ball into the middle of the pitch, it was crazy. It's hard to take, especially for me, because we played well.
"When you make mistakes it's important to bounce back and play better. I've made a few mistakes in my life and I'm still learning every day. I will learn from this."
The fault meant that the Reds saw their lead over fifth-placed Everton in the Premier League table reduced to just two points in the race to Champions League qualification.
