The Chelsea legend rolled back the years at Emirates yesterday.
Wenger laughed: "He did well when he came on. He still has the resources, you could see that yesterday as well. He has kept that physical strength and his intelligent game and he finished well.

"He [Drogba] took advantage of it. Honestly the penalty was very, very, very, very, very, very soft! It was classic Drogba."
