Open Question: Is Adedbayor Overrated?

With the talk of Arsenal striker Emmanuel Adedbayor transferring to another team, the figure of over 30 million euro has been thrown around.

To me this seems crazy!

Here is a guy who has had 1 good year in his career, which was this last season in which he scored 30 goals. Previous to this season he has never scored more then 12 goals in a season. 

Is a player who has only scored over 12 goals in a season 1 time worth 30 million euro?

On the other side, Adedbayor is only 24 years old, and still learning. He should have a bright future.
