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.
red card mistakes like that are sometimes difficult to avoid. Barcelona is currently still in a safe condition I think. the next match should not be a burden for Barcelona if Flick can still play his mainstay players in the squad.
what will be a problem for Flick is when some players finally can't play due to injury. of course, it will be very difficult for the coach to make a strategy when the quality of the players in the squad is quite different from the players on the bench.
Madrid also has problems with their injured players, but I think Barcelona will appear more consistent this season. hopefully,y they can maintain it until the end of the season.
