Suarez in a starter pack, Ramires, Oscar, Reus ( Kept him for my bundesliga ) and TOTW Koscielny.
I've had others like Welbeck, Lescott, Welliton, Giovinco, where I put them up for a relatively low start price and they sold for at least 5k on top of what I put them up for.
I've not even bought that many packs :p
