Your striker isn't born with Leo Messi's talented. He is just a code, just like every other striker. He is scoring purely because he had more skill points than the defenders have. What you do with thousands of tokens and green packs isn't a problem. Not really sure you need that much. Won't you get bored of winning every game with no challenge and barely any effort and time put into what orders you use? I give it 3 seasons until you disappear from the game.
The issue is you've posted an image of a striker who is probably better defensively than a 5* defender in your league and boasted you have no problem scoring goals. Either you're dumb or you're showing off. Either way it reflects bad on you.
I don't mean to insult you I'm just having my opinion.
