Haaland won't join Barcelona even if Barcelona are in good condition. Now they are in crisis and Haaland have more reasons to reject any offer from Barcelona. His style does not match with tactic in Barcelona and if he joins La Liga, he would choose Real Madrid or Atletico Madrid.
Perhaps Haaland will leave Bundesliga as well so his destination can be Premier League or La Liga. In my opinion, two best clubs for Haaland will be Real Madrid and Manchester City. Else, he can join PSG. They are top three clubs in my opinion for Haaland if he really leaves Dortmund.
I fully agree on the inappropriateness of Barcelona's style to Haaland, but disagree on the move to PSG. You can go to PSG only for the sake of money - this is a weak championship where a player will never become great and will not be able to write his name in gold letters in the history of football. If we assume that playing at PSG you can prove yourself in the Champions League, then I also disagree with this - real games in the Champions League are started out from 1/8 (and more often from 1/4) - it is very difficult to prove yourself at such a short distance.
