When a new season starts and when different teams play a few matches in the beginning we get an idea about different teams and accordingly predict a team that this team can reach this level this season but everything can be said about Real Madrid. It's not just that Real Madrid have strengthened their squad this season, they always focus on strengthening their squad in all aspects. And the most important thing is that Real Madrid has consistency and each player has a good understanding with each player which is why they are successful in almost every match and they will be successful in the next season.
The description of the form of play is not only seen in the Champions League because there may be other factors such as consistency of play in the domestic league. Although sometimes that is not a guarantee for them to play well in the Champions League or vice versa for many teams. For example, Dortmund played not very consistently in the Bundesliga, but they managed to advance to the final round where they were ultimately defeated by Real Madrid. Likewise, Arsenal and Man City played quite consistently in the Premier League, but they failed in the Champions League.
There are many factors that make a team play more consistently, especially in the Champions League because the competition in that league is quite tight. Experience, mentality and players and coaches really determine how they are able to reach the end of the final as champions
If the same team plays in these two tournaments of champion league or local league then the team has to play 2 strategies for both tournaments. A team in the local league will fight against an opponent in the Champions League, but the team will not fight against that opponent, that is, the opponents in the Champions League will definitely be difficult. The local league usually has 38 matches but the Champions League tournament doesn't have that many matches, only a few matches are played and a few matches ensure whether the team will advance to the next round or end their Champions League journey here. The teams that we always consider as favorites for the Champions League are always the best teams in Europe and based on their performances, they are placed as Champions League favourites.
