We are still in the middle of the league. Barcelona will definitely make a transfer. They have quality young players. If they add experienced quality players to these, I think they can finish the league in the top 5. I really wonder how they will form a team next year. If they take Haaland, 2-3 years later, a more experienced Barcelona can get much better results with the average age of the team.
It's true that Barca will make a transfer but getting Haaland, doesn't sound right. Raiola won't let him go anywhere if the price isn't right for him and it won't be "cheap". Barcelona has already issues with FFP, so it will be very strange to make an offer of such caliber. IMO these are just rumors and marketing, nothing more.
Why does Barcelona need Holland? This is too expensive a player. Barcelona has a lot of problem positions and it is crazy to give a lot of money for one player. It is better to take two or three good players for this money, who in the end can strengthen Barcelona more than one player.
The draw with Sevilla, where Barcelona played a third of the match against an opponent whose player was sent off, is a good result. From a tournament point of view, Barcelona was defeated yesterday - the number of matches until the end of the championship was reduced, but the distance to 4th place remained the same.
