Louis Saha gave Everton advantage after just 25 seconds into the Wembley stadium, but Didier Drogba tied to 21 minutes and Frank Lampard scored the goal of victory in the final 18 minutes.
The comeback gave Chelsea their first trophy in two years and its technical Guus Hiddink perfect farewell before he left office.
We were very hard and the team has always shown that it can react after a setback, which I like, Hiddink said. It was a great success, winning at the Mecca of football.
The FA Cup is something I can not believe.
The referee awarded a goal not to Florent Malouda for 78 minutes, when the French far from finished and the ball hit the crossbar, bounced on the floor and left the bow. Repetition television showed the ball had crossed the goal line.
Chelsea had other opportunities to shake the networks, the most important of Nicolas Anelka and Malouda.
I thought we were going through our best moment when Frank Lampard scored his goal, said the technician Everton, David Moyes. It is a great player and scores goals, and that's what I did.
Saha's goal was the fastest in a Wembley final for 18 seconds.
Drogba scored for the second time in an FA Cup final as the Ivory Coast was the author of the target in extra time with which Chelsea won the title in 2007 on Manchester United.
It was a great season, finished fifth in the Premier League and reach the final, but leaves a bitter taste, said the steering wheel of Everton, Tim Cahill. But it is an experience that can help me in the coming years.
