One can invest in all the facilities, get all the ads, and pay all the wages one wants. At the end of the day, what decides a football match isn't money. What decides a match is the players, and the quality of the game that they play. One can pamper a player, but it won't necessarily translate to good play. In fact, the opposite might be true.
Money isn't the be-all end-all for success. If it were, we wouldn't see all the rags-to-riches stories we know and love in the game. Players like Pele came from nothing and made it big with their own talent. Clubs like Wimbledon rose to success from humble beginnings.
With talent and drive, any player, or even any club, can make it big.
