Real Madrid are experiencing problems in their squad due to several key players being injured, their absence in the squad will affect the depth of the team which will make it difficult for them to win big matches. A big team name alone is not enough to achieve victory without being supported by a complete squad, in this phase it might be a little easier for Real Madrid, but when entering the next round the competition will be even more difficult.
The absence of these players will have an impact on their performance, If am not mistaken, I do not think Real Madrid ever played a game last season without Tchouméni and Camavinga, as both contributed to strengthening the defensive midfield. Both players will miss the Champions League game. A big team cannot win a game without great players. However, there is positive news for the team, Bellingham and Militao are training with the squad. I hope Camavinga, Tchouméni, and Mendy return soon, I do not want Real Madrid to be eliminated from the Champions League since, without the name, the competition becomes less interesting.
However, Manchester City is considered to be the favorite for the Champions League this season. But winning the Champions League title is always challenging. First, if you want to win the Champions League, you must have a consistent performance throughout the season. Champions League title is impossible to win if performance is erratic. If Haaland suffers an injury, City's performance will not be stable. Guardiola doesn't have a worthy replacement. They traded Alvarez this offseason. However, if Haaland is injury free this season, City have the potential to dominate the Champions League.
We cannot write Real Madrid off this season, I believe that you view Manchester City as the favorite team to win the Champions League because of the opponents they dominated this season. If Real Madrid defeated their league opponents in the same way that Manchester City did, I believe people would still consider them the favorite team. However, Manchester City were consistent in their games throughout all competitions last season, but they were unlucky to be eliminated in the Champions League by Real Madrid. You are right, Guardiola cannot rely on Haaland as a striker this season because his injury will have an impact on the team performance. Guardiola sold Alvarez to Atletico Madrid and has no striker to replace him, so he must get another top striker because no one can tell whether Haaland will be injured this season or not.
