Drogba missed a number of chances to put Chelsea in total command on Sunday - including one from six yards - before putting the Blues in front with a 71st-minute header.
Drogba said: "It was nice for me to score but not nice for me to miss the chances I had.
"The first one in the first half was difficult because of the bounce but I had a big chance to score.
"I was so sorry for my team. We can't be happy with the point - but we didn't lose. We still have a chance to win the next game, so it's okay. A point is a point.
"I am very disappointed and I think we created a lot of chances, I think enough to win the game."
Drogba was philosophical about the ultimate outcome - a 1-1 draw.
"Sometimes it happens," he shrugged.
"They had one clear chance and scored. I think they deserved a draw, because they defended very well.
"We created enough chances to win the game - sometimes you need only one chance to win, and every chance you create you score. This was the opposite, and that's football."
