Drogba: Chelsea DNA is to fight
"It is in our DNA to fight," he said.
"Nobody has really spoken about it but if Ashley hadn't stopped that shot, it would have been 4-1 and the tie would have been over.
"Petr that night proved himself to be the best goalkeeper in the world.
"All the saves he did today and before, in the other games, took us to where we ended up."
