#2 - Neymar needs to be at his best once again
Barcelona's man of the match for the epic comeback against Paris Saint-Germain was Neymar. He single handily won them that game. Sergio Roberto might have scored the winner, but it was all because of the Brazilian.
However, it's going to be very very difficult for him today as he is up against someone who knows his very well - Dani Alves. The right-back has played with him for several years at Barcelona and also for the Brazilian national team.
The defender knows his compatriot thoroughly and will be on his toes all the time. It would be interesting to see what skills Neymar has to get past Alves today.
Should Neymar succeed in getting past the Juventus right back at the start of the match, things will become one-way traffic from then on.
