If someone who doesn't know anything about football see when you people about how certain it is for Real Madrid to win La Liga next season, the person wouldn't believe Barcelona won it the season before last and Real Madrid won it last season. Barcelona won that league when they were going through a financial crisis mind you.
Your statement isn't clear, and it looks like you are not a person who understands well football.

If someone doesn't know football, how they will assume Real Madrid to have a better chance winning La Liga? If you don't know football, you must be not interested to talk about football, right? So it is impossible for someone who doesn't know football, they will predict a team to win a certain league. They must have no idea about Real Madrid and Barcelona.

Real Madrid are favourites to win La Liga, that's a fact, but why does everybody believe they're invincible with Mbappe? Is the attack the only part of team? I mean, this is Barcelona we're talking about and recently, they've been getting their affairs in order.
Unless you are Barcelona fan, you must understand why people favor Real Madrid to win La Liga again. Real Madrid could win La Liga last season, their chance will be higher when they have one of best strikers in the world now. It is strange if you don't understand it, only Real Madrid haters or someone with zero football knowledge who are not aware the big gap between Real Madrid squad level and Barcelona squad level for the next season.
With Flick, Barcelona stand a very big chance for next season's la liga. With the players he has and the players that Barcelona will sign, we would witness a very competitive la liga next season. As good as Real Madrid may be, I do not underrate Barcelona.
Very big chance? It is very funny you conclude it confidently.

Learn again the history of Flick's career. This man has no experience managing a team in La Liga. I even doubt that he will stay in Barcelona for more than 1-2 seasons. Dude, please wake up! Barcelona has no enough money to buy top players.
