3-1 victory in the Club World Cup against Mexican Champions Monterrey.
Match Report here
Interesting bit of this is with Romeu out for the season, Rafa played Luiz in a DM role rather than in the back line, and it sounds like it worked pretty well.
Edit: Just found a video of Luiz's performance v Monterrey - looks good
Looking forward to the Final on Sunday! C'mon you Blues!
