Actually the commercial value of shirt sponsorships have skyrocketed from last year. Take Arsenal. Man Utd, Chelsea and Spurs who all start new sponsorship agreements this summer (unlike us) - all four have seen large rises in the value of the market. One deal has spurred on the value of the other. In fact Arsenal who were the first of the four to sign a deal might be looking on a bit enviously now as their 8-year deal will be worth less per year than the other three.
