Lionel Messi scored four of Barcelona's five in their eventual demolition of Osasuna Sunday night at the Camp Nou.
The final scoreline wasn't quite reflective of the proceedings, as Barcelona benefitted from some controversial refereeing early in the match.
David Villa returned to the starting lineup along with Thiago and Adriano, but not surprisingly, it was Messi who stole the show with a hat trick and then some.
Pedro added a goal of his own to continue his scoring run and bring his goal tally on the season to eight.
The crucial turning point in the match was Arribas' dismissal in the 26th minute and Messi's ensuing penalty goal. From there, it was smooth sailing for the Blaugrana.
But there is still much we can take away from Barcelona's performance. Let's have a look at some important match reactions.
