El Classico will happen in 2 weeks. Exactly on matchday 11, El Classico will be held at Bernabeu. It'll be a high tension game again and again. This will be a very balanced and tight match, although many Real Madrid players are currently injured. but all will play with totality for this high tension and prestige match.
Carvajal is really unlucky with his injury. Even Hansi Flick made a statement on his injury by saying how sorry he was for him. Carvajal is still one of the best left-backs in the league.
As for the El Clasico closing in, I can't wait for it!

Barcelona are on a massive run and I really wonder whether Real Madrid will be able to stop them. Raphinha and Lewandowski are both reborn this season thanks to Hansi Flick. You know Yamal too. The kid is wonderful. In short Barcelona also has very deadly attackers just as Real Madrid has. A big clash is waiting for us.
Many will be looking forward to it because Barcelona and Real Madrid are in their best form but Barcelona looks more consistent compared to their arch rivals and of course Real Madrid will find it difficult to stop Barcelona even though Real Madrid has Mbappe, Vinicius Jr and Jude Bellingham it does not at all dampen the mentality of Barcelona players especially Real Madrid lost one of their mainstay defenders so this will be an advantage for Barcelona to be able to penetrate Real Madrid's defense, Carvajal is a defender who is quite strong in the back line his absence will certainly have a little effect on Real Madrid's defense especially since Barcelona's attack line looks more active this season.
This is home game for Real Madrid and of course it is very good advantage to be able to continue playing well even though they have some obstacles from some players who have to be absent due to injury, it just that I really have doubts that Real Madrid can win by landslide, it true what you said that Barcelona is much more stable at the beginning of this season.
Last match between the two in La Liga showed Real Madrid getting win but for now all the conditions are different, I think this match will end in draw even though Ancelotti uses all his mainstay players who can play later, Real Madrid defense line is quite weak for now.
All I hope is Barcelona inability to beat Real Madrid, with the draw obtained can make the difference in points between the two remain the same and of course the competition can be much fiercer for the future, now Barcelona is ahead by 3 points from Real Madrid.
