I've just got Sergio from my WL rewards, my best ever pull (since FUT began).
Two questions: -
1) is he any good/is he value for money, I used him in draft at the start of the game from memory was great
2) Even if he's great would you still sell as he may drop on the run up to TOTY?
I currently use Mertens and Larsson but would need to change my team quite a bit to fit him in.
