Oh Kolo, what were you thinking?
Liverpool were on the way to securing another three points - and in so doing go nine points clear of Manchester United and four clear of Everton in the race for the final Champions League spot - when the defender inexplicably played the ball straight into the path of Victor Anichebe and the West Brom striker duly scored.
With 23 minutes of normal-time still on the clock, Liverpool had time to rectify the Ivorian's mistake, but it was not to be, and Brendan Rodgers had to make do with a point from the visit to The Hawthorns.
After the match, Rodgers refused to blame Toure for the lost points. Speaking to Sky Sports, he said, "I'll never criticise players for trying to play football, but Kolo probably shouldn't have recieved the ball under pressure and his pass was misplaced.
"Kolo has been brilliant since he's been here. He's been a real leader, an outstanding professional and, unfortunately, it was a mistake."
But what did the fans think?
Well if you had taken to Twitter, or any social media website for that matter, directly after the match, you would have seen what I did - a flurry of anger and disillusion. But what about now, when Liverpool fans have had the chance to process the result and the events that led to it? Will they still be as angry, or will anger have made way for resigned disappointment and the acceptance that these things happen?
I took to Twitter again this morning to find out, and below are a selection of fan feelings:
Never mind the Kolo Toure error, what was Simon Mignolet doing with the pass to him in the first place? Same as Howard throw to Lukaku v WBA— matthewglazier (@matthew_glazier) February 3, 2014

Kolo Toure has vowed to learn from his bad decision. Pretty sure passing across your own box is something you are taught when you are 8?!— Wilson (@Snifferwilson) February 3, 2014
