But Barcelona is different from the teams you mentioned, although Las Palmas may sometimes provide surprises, but not Barcelona because this team is better and their players have started to strengthen the team again. I don't see Las Palmas beating Barcelona at their opponent's home base. Las Palmas must be prepared to accept a crushing defeat in this match.
Above all Barcelona is very superior, but sometimes there is another side where playing against a weak team often presents unexpected resistance. Of course this is only a small percentage for Las Palmas to come out as the winner. So Barcelona can still get 3 points and Las Palmas can still score goals, the difference of 2 goals is quite reasonable. Hansi Flick has no time to lose points because Madrid is still trying to survive in La Liga.
As long as they don't make any mistakes, especially unnecessary fouls, consistency will be easy for Barcelona.
Some of the defeats and draws that Barcelona have had this season have come from their own mistakes, which are too much to consider the opponent's attacks to have a big effect, which in the end when a momentum is obtained by the opponent then they will try to commit several fouls that end up with a loss for them.
Facing Celta and Monaco is proof that for Barcelona actually in terms of attack patterns and determination they are very good, it's just that they always make fatal mistakes that result in a red card which is punished by losing full points which they can actually still get in pre-match in terms of probabilities owned.
