The work of Barcelona will be even greater before they play an el clasico match. This is because their chances are slim if they are not able to beat Inter Milan. Victory is the only way if they still want to play in the Champions League this season. While Real Madrid will be easier, I consider this to be a strengthening of their game before El Clasico later.
Real Madrid must prepare well because they have the advantage of a tough Barcelona game in the Champions League. They have to see it as an opportunity for them.
Xavi's target is definitely the La Liga title. But a first-round elimination from the Champions League is a shame for Barcelona. Barcelona have spent a lot of money to strengthen the squad. They will definitely not want to be eliminated from the first round. So now their main goal is to win against Inter Milan. Barcelona will play against Inter at Camp Nou. Barcelona are always strong in home matches. On the other hand, Inter Milan will want to share the points by playing defensively. Winning this match is very challenging for Barcelona.
Barcelona have won their last two away matches against Real. And so Barcelona players will be very confident against Real Madrid. And the match will be very competitive. It is difficult to predict which team will win.
Xavi will do everything in his power to secure three point against Inter in the second leg of champions league group stage because the chances of Barcelona moving to the knockout stage strongly depends on the match. As for the El Classico Madrid is more emotionally prepared than Barcelona because Barcelona's focus at the moment is to save themselves from not qualifying. And after then they will just have 3 days to train in preparation for the El Classico. Xavi is under heavy tension at the moment in which Madrid can use to their advantage
