Barcelona may never lose, but if they draw a lot, it's also not good for them, because the points they collect are a little hampered if they draw a lot with the opponents they face. I think apart from defeats, draws are also one of the negative results felt by a club. Imagine me they feel 5 draws, that means there are 10 points wasted, and that will widen the distance from clubs that can get more good results with victory.
If we look back to last season in the Bundesliga, we will see how Borussia Dortmund failed to become champions because they only drew in the last match they played.
but it is also impossible for a club to win the League without a defeat or a draw. This is a long season, we will still see clubs losing or drawing, especially with the tight competition in La Liga.
the target of the fight may have to also look at their opponent. Even though we still have to hope and try to win, we still can't aim high when we see strong opponents.
A draw against a strong team is also good, and conversely, don't lose points when facing a weak team.
Strong team coaches usually rotate players when facing weaker teams, and that sometimes gives a surprise that a weak team can hold a draw or even win against a more favored team.
It's not impossible, but it's very difficult to do, winning the league without drawing and losing. I don't even remember and I don't know if there's a club that's managed to win the league without a draw and a defeat in a season. Some have experienced a season without defeat, but still they get a draw, yes it was done by one of the English clubs, Arsenal in the 2003/2004 season, it was 20 years ago.
One of the tough challenges they will face is when they play the El Classico match. Yes it is a very prestigious match and it is very difficult to predict who will be able to win in such a match, especially when the strength of the two clubs is the same.
Barcelona is currently one of the strongest teams in La Liga. So this team should win every match against the lesser teams then their position will be good in the points table, which I think will come in handy in the latter stages of the league. But something better can be expected from the Barcelona team this season.
