This is the post that started it, you stated he was 81 million and I stated that no one includes salary when they show the transfer fee of a player. It really is simple mate. Going by your "logic" Gylfs trasnfer was 71million when we ALL know it was 45.
You're not understanding it still.
You have to commit to a wage so yes, the deal was for £81m. Maybe Juventus were willing to pay the £45m in fees but not commit to the £36m in wages? Maybe that's why Dortmund got him in the end? It's all important.
