What are the best chances i have without leaving the US of meeting Chelsea FC or watching them play?

Its my dream to shake the hand of my idol Didier Drogba, i had a chance 2 years ago in 2009 when they came to baltimore . my home city. i didnt get to get an autograph from any chelsea players than because of lines. they then swtiched ac milans players (who were chelseas opposition for the game the next day ) in to sign autographs. if the chances of them coming back to the states are gone. is there a almost sure-fire way to get his autograph from england without paying an arm and a leg?
