As a neutral observer, I read up on this shit when we were linked with Talisca. From what I understood he had a massive ego and the Benfica coaching staff didn't really care much for it, he wanted to be a leader and the best player (and he probably was the most talented at that point) and they wanted him to show humility. Can't teach a cow to fly. So he demanded to go on a loan and threw fits until they let him go (I forget all the things he did but I'm sure at some point he was with B team).

So once he went on a loan he didn't get paid the first month or two months and got angry because at that point he had a little girl that he was raising by himself iirc. So he got really angry because Besiktas owner and the manager convinced him that Benfica had to pay his salary for that time, while Benfica were saying that Besiktas has to (or that they did, I forgot), so he felt that Benfica are a bunch of cunts who want him and his daughter to starve.

Well, he's a self important hot shot who probably acts the way he plays, cocky, electric and unpredictable. But it looks like both sides fucked up and wanted to finish with each other asap.

Everything else that can be added to the story can be attributed to the product of this above.
