Arsenal vs Barcelona prediction (Over/Under)

Tonight in London expected us a very interesting match between Arsenal and Barcelona. There is no doubt that the Catalans are favorites or not exclude the possibility that Arsenal pulled out a favorable result before the rematch. I decided to cartons. The tradition of their games mostly with 4-5 card, mostly Arsenal players. The reason for this is what Braselona always had excellent strikers that hard to stop, the only foul. The English men play a strong football. I expect the pressure on the top players of Barcelona. The only way d aih stop, road closures, foul in the middle. This game is mainly for judges of the judges sanction records.
