I agree with you. Barcelona is a renowned club. There is no way to take this team lightly. However, it is very difficult to dominate La Liga with this Barcelona squad. A strong squad and consistent good performances are essential if they want to dominate La Liga and win the title. Barcelona's squad is not too weak. However, this squad failed to perform well consistently. This is why it will be very difficult for Barcelona to dominate La Liga next season if the squad is not strengthened. I am looking forward to see Hansi Flick's match strategy. But hopefully with the help of Flick, we will see more improvement in Barcelona's performance.
Barcelona's results were not bad, they were simply unlucky in the Champions League, if not for the red card, they could have achieved much more, which means in this case it was not a weak team, but simple bad luck. In La Liga, not everything is so bad, it’s just that Real is too strong now, and Girona is also to take points from Barcelona, such a fact, but this is like an exception that may not exist in the future. Flick has got an excellent team with which he can achieve good results.
Maybe Barcelona's performance wasn't so bad. However, it is not possible to dominate La Liga if you perform like this. The performance of the Barcelona team was not stable. We haven't seen Barcelona play well, especially against the big teams. Barcelona's defenders can't do well against big teams either. This is why Barcelona have conceded a lot of goals in several matches. If Barcelona want to win the La Liga title, there is no choice but to improve their performance. The squad needs to be strengthened. However, if Barcelona are happy to keep the second place in the table, then Barcelona can keep the squad unchanged. Because while Barcelona's current squad lacks experienced players, the squad is strong enough.
