A big win over Arsenal would help!
The only important thing against Arsenal are the 3 pts. We have another difficult game in 3 days, then another PL game in 3 days, and then Real away in 3 days. That's four difficult games in just 10 days. Our GD would be the last thing Pep would think about in this period. It's all about points in the PL and a good result at Bernabeu.
