Rafael Benitez admitted he was a minute too early taking Robbie Fowler off to give him the chance of a standing ovation from his adoring Anfield fans.
The Liverpool chief opted to withdraw Fowler with two minutes left, and 60 seconds later the Merseysiders were awarded a penalty.
The Kop erupted into ''we want Fowler'' but by then it was too late for the skipper-for-the-day to step up and sign off his Anfield career with a spot-kick in front of the fans who idolise him.
Charlton had led twice, through Matt Holland and Darren Bent, but Xabi Alonso and then Harry Kewell - with that penalty - gave Liverpool the point they needed to clinch third spot.
Fowler was playing his last game in a red shirt at Anfield before his contract expires, and Benitez said: ''I was just too quick. If I had waited a minute more, Robbie could have scored from the spot in front of the Kop, that would have been a perfect way to end for him.
''I had wanted to give him the chance of a personal ovation, but it was just one of those things in the end. It was just bad luck for him, but at least I made sure he got the ovation he deserved.''
Benitez added: ''It was not a good game. We made too many mistakes and it was not easy with the Champions League final at the end of the month. They had other things on their mind.''
Charlton boss Alan Pardew had seen his side bid farewell to the Premier League with a display that will give him confidence for next season.
He said: ''Liverpool have a habit of scoring late goals against me, it happened in last season's FA Cup final against West Ham.''
That final was exactly a year ago to the day, and Pardew still had kind words for his former club.
He said: ''I am delighted West Ham stayed up. They have got back their fighting spirit in these last few weeks and their form.
''I am pleased for them and for a lot of good people at Upton Park that they stayed up.''
As for Charlton, Pardew said: ''I had tried to make sure we were positive all week after our relegation was confirmed. I wanted us to play with a smile."
