EA Sports have released a Flashback Diego Costa SBC and that card looks really good. The Atletico Madrid striker has been handed an 89-rated card with a shooting of 92 and 96 physical.
The best chemistry to use on this card would be Marksman as it takes his stats to 95 overall! His shooting stats rocket to 97 with Positioning and Finishing at 99 and Shot Power at 98!
The SBC is just one challenge and all you require are 2 Team of the Week players (in form cards), an 84-rated squad with 70 chemistry. The SBC cost me nothing because of the untradeables I had in the club but the overall cost (with loyalty), when checked on Futbin, was just 68k!
