If Barcelona use the strategies they used on inter Milan match to play Real Madrid on October 16th, I think it will be difficult for them to achieve victory from the match, because they struggle to draw the match 3-3 with inter Milan. Since Real Madrid performance has reduced in this season compared last season, Benzema used to achieved many goals in every competition but this season he find it difficult to achieve many goals. I think, Barcelona will definitely achieve victory from this match because Robert Lewandowski will definitely achieve goals that will bring the team victory at the end of the match.
This is the biggest conceded for Barcelona since the start of the season, previously Barcelona only conceded at least 2 goals in all official matches this season. The absence of Araujo and Kounde was felt in Barcelona back line, Barcelona defense looks fragile without the presence of these two players.
Xavi must be able to close his defense meeting so as not to concede many goals in El Clasico matches, because the quality of the team owned by Madrid is stronger than that of Inter. Madrid could embarrass Barcelona if Xavi did not close the gap in the defensive position, especially in this El Clasico match Real Madrid will act as the host.
Xavi has built his main squad quite well. especially their defense which is getting stronger at the start of this season when compared to last season.
but with the absence of several players who were Xavi's main squad of choice, of course, it was a big hole in Barcelona's defense. El Clasico will probably be scarier than the match against Inter. it could be that Barca didn't have a chance to attack. I hope Xavi has found a strategy for his squad shortage.
