However, we also have to look at the quality and performance of the current Barcelona team realistically, Barcelona has not played well in the last few matches and there are many things that Xavi must immediately fix to make this team much more solid.
I would not be surprised if Barcelona's next match will reap bad results because in my opinion the current Barcelona team is not very strong, especially their bottom line which has conceded a lot this season, especially in the last 2 matches Barcelona conceded 4 goals, that's not a good thing.
And also Xavi's team is currently not well organized, so if they meet tough opponents, I doubt Barcelona will be able to win, but again, if it's still early in the season, anything is possible.
What exactly do you not like about Barcelona that they conceded 4 goals? So they missed 3 of them in one match with Villarreal and by the way they won this match, but it was the kind of match when the teams went for a counter game, Barcelona rarely allows this. Barcelona sticks to their previous strategy, they play well in defense and do not try to score many goals, their main focus is on the result. Quite a good start to the season, one draw and three wins, so I don’t see any big problems for Xavi’s team.
I prefer to think that they are struggling to score goals rather than not trying to score many goals in a match because looking at their condition for the beginning of this season it seems very difficult for them to score more than 2 goals in 1 match.
There still needs to be some familiarisation when trying out some of the younger players and Lewandowski's performance is still hampered by the opposition's marking which makes it difficult for Barcelona to find many goals in their matches.
Despite this the chances of them winning definitely remain as they are the favourites and the worst possibility is a draw although this would be difficult for Betis to force a draw.
