As I said before that Barcelona will definitely not score more than 5 goals in this match, even though Barcelona has quite good statistics when beating Real Madrid with a big score but that cannot be a reference in this match will be the same because each team has a different defense I'm not saying Espanyol's defense is better than Real Madrid but this club can at least withstand many attacks from Barcelona and finally only conceded a few goals.
You don't expect Barcelona to score up to 5 goals when they have an important engagement in the champions league, Espanyol is the least of their problem and the game yesterday Barcelona have already won it before the kick off because from what I saw if the ref gave them 3 more hours as additional time Barcelona won't mind to make the game uncomfortable for Espanyol. I felt for the away team (Espanyol) because the more they try to give themselves hope of coming back the goals they score is being chopped off, that alone can kill the spirit of a struggling team.
This team I'm seeing now can go along way and my hope is that they do get someone to replace Lewandowski and some other guys so it won't weigh them down when the time comes because it would be a disappointment if Barcelona still have that idea of relying on one player for years until the player chooses to leave or stopped performing as good as he used to, they whole team will start struggling with form, same thing happened to these same Barcelona during the times of Messi, Xavi and Iniesta, nobody was their to replace these guys and Barcelona suffered for it so it would be nice to always have a plan B.
