I thought with the second video in portuguese you would understand since it is close to spanish. But this is an english speaking forum after all, my bad.
They cut the questions from the video and only included his answer but you can deduce from that what they were.
He is asked questions about the game. Says he is happy for the team and himself. That his job is to score goals, thus he could not be more satisfied and happy.
Then, he is asked question about his future. Says he is happy at PSG, his contract is still very long, 2021 or 2022. It is not time to think about that matter.
Then, i think press must have insisted again and then he answered what chiringuito is reporting : you never know what will happen tomorrow but all i can assure you is i'm here for this season and after that, we'll see.
The way, he says it is more like he wants to stop talking about the subject and gives that generic answer to cut any debate. However, if you report it out of context or seeing the video, you might believe he is opening a door.
About PSG stance, they would never be tempted by any amount of money. Same with Neymar.
They only way they leave before the end of their contract (bar exceptional circonstances such as terrible injuries, exit of Qatar for whatever reason etc.) is the FFP. PSG knows they have to balance the books, so depending on TAS and UEFA ruling, they could be forced to. But then, Real Madrid would be heavy favorite due to excellent relationship between the two clubs.
