It is true that the players recruited by Xavi Hernandez showed that they deserved to be chosen to be part of Barcelona. Aubameyang is one of the best signings in my opinion, in this match he also contributed greatly to Barcelona's victory by scoring two goals. And also Xavi Hernandez is the best signing also in La Liga by bringing Barcelona out of adversity.
I think Barcelona also deserved a very good performance because the Barcelona team in the past was very famous for the achievements it carved in several Leagues before falling and now Xavi Hernandez has returned the Barcelona form that was lost by bringing some new players into the team, so Barcelona deserve to win for this match.
