Drogba literally didn't touch Fabregas, he dived, that's hardly embellishing, that's complete fabrication. He flings his legs back, football is the only place where people fall upwards. It's a really soft penalty, it's basically saying that any missed tackle in the area should result in a penalty. Fabregas touches the ball away from goal to win a penalty, he's anticipating a foul but it never comes. It's in clear view of the linesman and the official by the side of the goal, probably the referee as well, really bad by all of them.
