Yeah, but like I said, is there no way you could employ an agency to just handle sponsorships and endorsements? There's probably loads who do just that, we wouldn't know. I just find it strange you'd hand somebody a huge percentage of a transfer fee, especially if you're a top player, when you could just appoint somebody with legal expertise, on an hourly rate, and they then become de facto agents. Pretty sure they'd have the brains to send some emails out if you wanted to gauge interest from other clubs.
But hey, what do I know, just find it an interesting topic. Mainly because I hate them barstewards taking the sums they do.
