Manager index continued...

After my last post I did a bit more experimenting with the manager statistics. This time I've added a second Bulgarian manager -- Yassen Petrov, the current manager of Levski Sofia. Since both Stoilov and Petrov started their careers roughly the same time, it's interesting to see how they stack against each other. Feedback is always welcome. Enjoy! :)

Edit: I've now added Ilian Iliev, the manager of Beroe to the mix.
