It's alright for Rooney and Co on their all expenses paid jaunt to South Africa. They earn more in a week than the average fan earns in years. For the fans that went out there, they will have incurred large expense. Not saying that should guarantee victory but the fans deserve better than that. Plus, and I watched the game in the pub so I may be wrong, but they only seemed to noticeably boo after the game so if Rooney is looking for excuses, he'll need to look closer to home.
Correct, it shouldn't guarantee a win; however, it should guarantee a performance, which the fans were robbed of.
Oh, and I don't want to see the players on the TV post-match saying "it wasn't good enough". Save your excuses. The only thing I want to see/hear is the players giving it their all and at least trying to win.
