Yeah it's just Barcelona's and their fans dreams, don't take this joke too serious.
I see no reason Haaland need to move to other teams since Manchester City currently the best team, Real Madrid also one of the best too, but they already have Mbappe. If Haaland intention want to join other team to collect more domestic trophy, he should move to Inter instead.
Inter is a rich team and they also have a good squad too.
Yep. It seems impossible to sign Haaland now. Haaland feels happy with Man City, he has no bad issue there, he has huge price, and he has too big salary. With these conditions, there is no way for Barcelona management to sign him. Even, I doubt if Haaland has the interest to join Barcelona because Barcelona isn't a very competitive team now and they have some problems, especially financial problem.
Joining Real Madrid looks like a more possible but I think it won't happen until his contract expires. Haaland still has a contract with Man City until 2027, I heard no rumor that Haaland will leave Man City before his contract is over. So, it is also very unlikely that Inter Milan possibly signs him, too. Even if Inter Milan has the money to pay both the transfer fees and his salary, it can't happen if there is no interest from the player leaving the club. IMO, Haaland is focusing his career at Man City now. The exit rumor is a rumor only, there is no official statement from Haaland.
It sounds impossible for Haaland to be recruited by another team while his contract at Manchester City is still quite long, but anything is always possible and not impossible. Even Barcelona could surprisely bring in Haaland in the following seasons even though we all know Barcelona has financial problems which prevent them from bringing in expensive players.
However, Barcelona does not need a center forward at the moment, of course considering that they still have Lewandowski who is playing well as expected. Some reserves are also there for the centre-forward, so they don't need another centre-forward unless they see something needs to be added.
