Obviously, both the Madrid's won't win all the games. Barcelona just has to be consistent, but I don't see that happening with the current young players this season. One game they are scoring 5+ goals, The other game they are losing to a weak team thanks to bad defensive tactics.
Oh yes, Barcelona inevitably has to rely on young players, and at this age it is not uncommon for a young player to experience ups and downs during the season for purely physiological reasons, when the body is growing and the body is being rebuilt both physically and psychologically due to hormonal background. However, there are fewer such fluctuations in adulthood. In principle, many people, including me, were surprised at how Barcelona started the championship against the background of its problems, so the recession was inevitable and now it will be interesting to see how Flick will be able to cope with this situation.
