I bet that Haaland not only will continue to score goals like that, but he will also score a lot more. The main reason is that everyone is tightly marking Haaland now, which results with him not being able to score that easily, but if he can't score easily, then how could he score more?
Erling Haaland is constantly hungry for goals, and I have no doubt that he will continue to score even if he is well defended. Remember, Pep Guardiola is still their coach, and he always has a way to modify tactics and plan throughout a game in order to help the team win. Erling Haaland will still compete for a spot among the top scorers in the Premier League next season.
I hope Xavi can really learn from Barcelona's mistakes and his strategy in the last two seasons in the Champions League, so he should have a good plan for next season's Champions League. But still, I don't think Barcelona has a big chance to win the Champions League title soon.
He has already shown a few improvements in the team, so why not consider him a contender for the title in the coming season? I understand that winning the Champions League is difficult due to the large number of great clubs that must be defeated. I don't think any team is better than the others right now, but we'll have to wait for the league to start before we can speculate.
