Got Ogbonna and Lamela, only got 7k from that. Spent that on packs and the only thing that will get me coins is the Seattle Sounders third kit I got, very nice with the Xbox 360 logo on it.

My daily gifts were Bronze gift pack, Bronze gift pack and luckily for me EA gave me a Bronze gift pack today!! My starter packs weren't much better, the rares in my player packs were Lee Hughes and some unknown bronze Serbian CB that plays in Serie B. I have had no luck thus far but hoping my daily gifts from now on are a little better.
