Even before Fabrizio Romano disclosed that Kylian Mbappe have signed for Real Madrid and would be unveiled anytime soon by the club, I already have seen enough reports that have me the assurance that Kylian Mbappe's next destination will be no other place but Real Madrid. The France international is one player that's very curious in actualizing his football dreams of winning the UEFA Champions League trophy as well as winning the Balon D'or award of which he knows will be easier to get at Real Madrid.
Talking about Barcelona and how they'll find it different to face Real Madrid or challenge them in any of the Spanish domestic competitions come next season, I think the Catalan club have already made peace with the fact that they can't match Real Madrid's strength fir now. It's almost impossible for Barcelona to challenge Real Madrid come next season.
Indeed, before Fabrizio Romano announced it, we were still 99% confident that Mbappe would go to Madrid, yes 99% because there was still no truly credible confirmation from either Fabrizio Romano or Real Madrid themselves, who preferred to remain silent and focus on UCL. Then after Fabrizio Romano wrote "Here We Go" what was initially 99% became 100% full without any more doubt, without any more question marks in the Mbappe transfer speculation. So basically this announcement from Fabrizio Romano is a piece of the puzzle to complete all the drama related to Mbappe departure from PSG. When the puzzle was completed, the transfer world suddenly became excited because everyone had found the missing piece.
Now that drama is over.
Some time ago on Real Madrid's official social media they confirmed by uploading a video with the caption “WelcomeMbappe” so surely now what Fabrizio said was immediately responded to by Madrid and indeed I was not too surprised by this

SourceAfter several seasons of Madrid, Mbappe and PSG drama, we are finally given certainty by seeing Mbappe really in Madrid uniform for next season and this is clearly the best thing after Madrid could bring Mbappe on a free transfer.
It seems like this season is a very good season because apart from the Champions League and La Liga trophies that they managed to reclaim from Manchester City and Barcelona, they also managed to bring Mbappe for free which makes Madrid even more confident to navigate the next season.
