That is common mis-conception. Barca have traditionally not been one of big earners in terms of revenues. Although they are a big club and an European Champion, Barca is probably not in the same level of class with Real, Milan, ManUre, and last year's Juve. Their great fans creates this illusion of granduer which are rarely matched by the play on the field, and activities outside it.
Once we get promoted, I presume we will recover 30% of our lost revenue from T.V. & Nike deals, which will put us near top end of the earners lists. Additional 10 or 12m Euros we get from shirt sponsorship isnt that critical to our success next year. The matter of fact is the deal won't be anywhere near big as Tamoil, and if that is the case it makes more sense to boost our image for long-term future. Whatever the reasons, our club seriously needs to boost up our image around the globe if we are to be connected with next generation of fan-base.
Beside, I feel Red-Cross at the middle of our shirt will look great. Kind of like Crusaders, only that we are fighting an evil called Inter.
