Other than the £2m a year we get from them then I'm still not convinced this is going to help Evertons brand much, I don't think any shirt sponsorship really does, it helps the sponsor.
We are not sponsoring them, as far as I know they aren't going to advertise anything Everton related.
I've just had a browse on their websites and can't find 1 thing Everton related. They are a much bigger brand than us but are obviously using us to get some advertisement in the PL, I don't think the size of the brand makes much difference to the football club, it's about how much money you get. 1 look at the top teams sponsors will answer that. Hopefully Rovio paid more than anyone else.
