Essien told The Sun: "The goal against Arsenal is the best in my career. To score against one of our rivals from that position and at that time of the game is something special that I will never forget in my life.
"But I think I can score better goals than that. Once I keep believing in myself, I can score beautiful goals.
"Personally, it was a fantastic season for me and I was very happy with my output for Chelsea.
"It was not easy for me and my team-mates and we have to be happy that, after a difficult campaign, we managed to grab two trophies.
"Hopefully, next year we can all do even better.
"Although we finished behind Manchester United in the league, I think they deserved their title. They put up a great fight from the start to the end of the season.
"As Chelsea, we can't win all the time. We won two trophies in the end and I think we were OK with our season. But we'll try our best to win back the title."
