Utd's past and potential future success and how many shirts they may or may not sell are already taken into account when the deal was negotiated. As would any marketing stuff Utd may or may not have to do. Beckham may have still been a Utd player when the deal was negotiated; Nike didn't cut what they were paying Utd when he left, did they?
As I said in my last post to Frank, it does make some difference but it's massively exaggerated and wouldn't pay a fraction of a star players wage. And it's even less relevant in very short deals like Beckham on a 6 month dea, as we've been discussing.
Yet Rooney's past performance should take into account roughly how much he scores, and do away with a goal, assist/appearance bonuses and based on the average number of titles Utd win that would be factored in. Meaning everyone gets a predetermined wage based off their average........ except, that does not happen, at all.
UTd shirt sales should grow year on year, they simply won't know how much and a year in which they lose 5 star players, selling and retirements could have a significant effect, as could buying a couple of huge star names.
Again, you think Utd won't factor in the CHANCE they might sign a megastar type who would be worth more to them financially..... and lock themself into a deal that won't increase their earnings...... not a chance. You know why no chance, because I thought of the idea of a deal whereby if they signed someone who was worth more in image rights, then Utd make more. Several other people here thought of it...... that means Utd thought of it, that means Utd did it. You know how I know Utd did it, if they were a crap team BEGGING for shirt sponsorship they take what they can get. Its utd, sponsors are begging Utd to take them, not the other way around, that means playing off one company against another to get the best deal.
I don't buy for a second that Utd wouldn't have a either a bonuses based on various shirt sale targets, or a clause that increases payments based on who they buy, in their deals, because it would be throwing away money not to and they don't have to be picky in what they ask for because if one company won't offer it, another will do to steal the contract.
