At 36, Drogba has been forced to adapt to a bit-part role at Stamford Bridge this season.
He said: "I've only lost once at Wembley - and we all know who that was against!
"Losing against Tottenham in 2008 was a difficult one to take because I had just returned from the African Nations Cup and we started well (Drogba put Chelsea in front), but we lost to the better team.
"It is not easy for me to pick out one goal or match as my favourite, but if I had to choose one Wembley memory it would probably be my free-kick against Portsmouth in 2010.
"But it is very important for us to win on Sunday, in the same way that it was important for us to win this competition in 2005 during my first season at the club.
"That gave us a big boost, knowing we could win things together and achieve something special if we all focus in the same direction. It was a big step for us, and winning it again would be a big step for this generation of Chelsea players.
"Put me there on the pitch if you want to see how much it means to me, or how hungry I am to win more medals."
