Youve got already profit when you bought Naingg for around 130 k and they just released packs and he is still in packs. So you make profit for sure. If its 10 or 50 k per card doesnt matter as long as you are making profit.
Pires - Ive only played 4 games with him in FUT-Draft but he felt like a weaker version of Schürrle. Not worth that much coins. He felt slower, weaker and missed few easy shots. Atleast his passing was good.
So not worth the coins? Thinking about getting him later on. Only played 4 games with him and yea he was indeed pretty weak. Feels like a better Douglas Costa. Not sure if he is worth 1,4 mill.
If you dont have that much coins i would pick a cheaper target. The higher the price the higher the risk. But i think 40k is a reasonable price, but he could drop more if there are 50k packs today.
