The games were easy for Barcelona
I will like to see how Barcelona will play against bigger teams as the competition continues.
If Barcelona can perform like this or any of give a performance that is close to any of their recent La liga perfornance, then I think they would do fairly well. Barcelona in recent times look very strong and I'm rooting for them to go very far in the Champions league this season because whether we'd like to admit it or not, Xavi's current team is a well rounded team. The additions of Gundogan, Cancelo and Felix was a very good decision. One that has already started paying off.
Barcelona is better than the previous years, winning big, 5 goals to 0, and so on...
This doesn't mean Barcelona is a strong tram since they played vs weak team from Belgium called Antwerp.
The real performance will be evaluated when facing teams like Manchester City, Real Madrid, PSG or Bayern Munich.
PSG did a good job scoring 2 goals to 0 vs Dortmund. Such victory will be very important for the second leg game.
