Although Real Madrid has now added mbappe to their squad, who will make them stronger, if Barcelona doesn’t add more effort to get more talented players that will face the performance of Real Madrid, I think they will definitely maintain that second position, which means winning the title might be so hard, but let's see how the transfer market will be before the season.
What you said is the reality. What Barcelona needs to do is to focus on enriching its squad depth to be prepared for the next season which is obviously going to be a tough one as upcoming clubs are warming up to take the space, clubs like Girona and Leverkusen did well in their own table leagues while other elite clubs are already gingered to work harder next season hence the change in managers currently happening across the clubs and the reformation some of those clubs making right now. So Barcelona must join the train to and make some tactical decisions concerning their squad depth to make them more fierce.
Barcelona spends more on defence while xavi was still around let's see what the new coach decision will be and they need to stop holding alot of players what're not contributing like they used to do, I think it's pretty much reduced ...
Now competing with Real Madrid can't be really decide at the moment but viewing it logically we might say they can't compete with Realmadrid currently with their squad , a squad is just a team of good players and a player doesn't have to be known world wide before you can determine he's a good player depending on his performance... however,getting their current team to perform even better could yield a good result and no doubt that the squad is weak truly
