The riding the wave of immense fortune thing, We can go way back and trace the successful period of any club to a time when they got a massive injection of cash.

Next it was ironically an year in which we did not spend that we became champions.

Lastly the rules are now structured in such a way that those who qualify now will forever shut the door on those who don't because of the vast difference in cash and the spending restrictions imposed due to FFP

Chelsea are now 5th in the world in cash generation behind Manchester United, Bayern Munich, Real Madrid and Barcelona all of whom have bigger stadiums.
So ya I'm feeling pretty good especially with the news that Mourinho will probably be back next year.
