Totti struck both goals for the Giallorossi.
"The result was my fault and I shouldn't have got the penalty saved," said the captain of a 2-2 draw with Catania.
"It's a point that feels quite useless. Unfortunately we were unable to win and I think my penalty was decisive. I take full responsibility as captain.
"As for the goals conceded, those are down to everyone, because when the defence is exposed it's because the strikers aren't coming back to press the ball. We must remain united to overcome these moments."
