Yes, as a French fan I can confirm Dembele loves Barcelona and there's zero chance he leaves anytime soon... I doubt Barcelona board ever thought about selling him either, it wouldn't make sense at all after splashing so much money, especially when Dembele showed multiple encouraging signs of adapting.
What is true is he may be sometimes a bit shy like very young players usually are. Injuries didn't help him either. Barcelona slow style of play isn't a perfect fit either.
But in terms of raw talent and potential, no young player outside Mbappe is matching him. Both are incredible players, nobody else comes close as young players... Mbappe just grew faster last year due to Dembele injuries and lack of playing time, but I think Dembele will be on his level or better if given ample playing time and confidence.
Barcelona should sometimes play a more direct and fast football though, they'd benefit greatly with players like Dembele or Coutinho.
And VV shouldn't ask Dembele to become something he's not like a midfield or a basic winger, that's not where you'll get the best from him. You must do a bit like Tuchel did at Dortmund and let him relatively free to create, that's where you see the real Dembele, the one who kills games all by himself, like he did last game.
