I suppose they will take a look on what happened there and will improve it, so again, I believe that Real Madrid should start the game with the spirit that they are facing a furious team, not the one that failed against Inter.
If you look at Barcelona's performance against Inter today, it is quite balanced if in the end they are directly met with Real Madrid. The most anticipated match in La Liga. Both clubs have been pretty good so far even though Barcelona was unlucky against Inter. Xavi's focus is still on La Liga, he realizes that their current quality is still not ideal in the Champions League. The return of Franky De Jong and Kunde added to Barcelona's power. Despite playing at home to the opponent I hope that Xavi does not waste the chance to decide who deserves to lead at the top of the table.
Barcelona is in dire straits in the Champions League. They will definitely now focus fully on La Liga. Barcelona will certainly not want to lose the top spot in the points table at the moment. Because qualifying for the next round of the Champions League is completely uncertain for Barcelona. As Barcelona have won the last two away matches against Barcelona. Therefore, in the next match, Barcelona players will be confident to win against Real Madrid. On the other hand, Madrid's performances this season have been very consistent. Coach Ancelotti is very experienced. I think the match is very likely to be a draw.
Barcelona is highly sloppy, Xavi frequently makes mistakes with his lineups, and the defense has a big impact on the team's performance and outcomes. They must bring in fresh defenders. if they will finish in the league's top four.
El Classico is this weekend; Barcelona shouldn't anticipate anything else than losing. They now cannot compete with Madrid because they are not on Madrid's level. They will be eclipsed by Madrid.
Madrid will win the El Classico since Barcelona's team is inexperienced compared to Madrid.
