Real Madrid will secure and consolidate their future with the Mbappe transfer for sure. I'm very confident about it and I don't expect him to have adaptation problems. Fabrizio Romano has already tweeted Mbappe's official deal with Real Madrid by the way. 
Real Madrid or Mbappe haven't announced the news officially though as far as I can see. But after the celebrations they would also surely announce. I trust Fabrizio Romano as a source as his news are correct nearly every time.
Anyways, from now on I'm looking forward to watching Mbappe in Real Madrid jersey. He is really hungry for Champions League titles and much more meaningful domestic titles compared to the Ligue 1.

I'd say ninty percent of us knew about it and that his final destination was going to be Real Madrid after failing Florentino Perez some years back, he wouldn't want to do that again. This is a smart move for him and this was his personal decision and not that from his parents who had influenced his previous decisions to stay with Paris Saint Germans.
I see him as a man now, and a fully grown adult capable of making his own personal decisions for the next phase of his career. I'm sure in the next three seasons, he'll be kicking to be the next Ballon d'or winner.
They Real Madrid should know they have a war lord in La Liga Competition right now, Hansi Flick is tactically brilliant and intelligent I'm sure he'll disturb all.of La Liga with the squad that he'll build, I'm anticipate what's his got in between, I want to see him successfully doing what he loves.
Barcelona management will do all they can to help build him a fighting squad. He could influence David Alaba to move to Barcelona, I'm certain.
