The Liverpool boss will show his defenders clips of the Chelsea striker throwing himself to the floor so will be wise to his cheating ahead of Wednesday's game.
"I have a lot of film clips of Drogba from over the years. So I was really, really surprised to see him on the ground so many times - no, really after four years I'm not surprised at all. He's very impressive at doing that," said Benitez.
"I have clips of him falling over every time. I have shown some of the clips to some of the players.
"I think with Drogba you need a clever referee. It's important to have a good referee. It was so clear what the player was doing in the first leg.
"Look at him. He's an amazing size. He's massive. But he always falls over."
