I think it just goes to show that things change so fast in football, clubs should not sign any deal longer than 4 years.
Man Utd's deal dwarf everyone's deal, not just ours, the next best is Real Madrid's deal and theirs is £35m a year. The question I would have is; How will this affect the fans? Nike pulled out of the deal because they did not think it would make them money. I would not be surprised if this means that Man Utd Adidas shirts will be between £90 and £100 (like Nike did with the England shirts) to make it pay.
Would you be happy if the shirt price doubled at Everton?
