10 years sounds too long in my opinion. With the way how football is evolving now,... risky.
Keep in mind this: Right now barça has top 3 worldwide because of MSN and Iniesta. top 4 players. In 6 years only Neymar will be a top marketing player.
And also almost every big clubs are signing 10 years deal.
Lets be realistic: we´re talking a billion euros. Nike has to protect their business.
It´s the sponsor deal that we need to improve.
United Chevrolet´s deal needs to be the example.
