Personally I don't know where that reaction comes from, Chelsea played a team that were (on paper at least) better than them, in their back yard. How else did anyone expect them to play?
Scenario: England meet Spain in Euro championship finals.
If England were to win the Euro championship playing the way Chelsea did tonight, would you:
A. be delighted, citing Roy Hodgson as a tactical genius, & the players as truly 'world class'
B. be delighted, but deep down feel a little embarrassed about the way we won the trophy, acknowledging that there is much work to do in order to be recognised as a footballing nation to fear, a la the Spanish
C. not really care how we won, just be delighted that we won the trophy
