Barcelona have not started well in La Liga so far this season and drew their first game against an easy opponent. Now they are playing away against Villarreal and are losing so far, but the match is not over yet. I think it would be better for them to get into the Europa League like they did last year to try to get to the final. In the Champions League it will be very difficult for them.
In the end, Barcelona was able to narrowly win after Robert Lewandowski scored a goal in the 71st minute for Barcelona so that the home team had to be willing to lose to Barcelona because they were unable to equalize in the remaining time or after Robert Lewandowski scored the last goal for Barcelona in the match. I think Barcelona is still good enough to compete in La Liga this season even though they had a draw in the opening game this season, but for the Champions League I still doubt Barcelona can do better because there are many teams who will show their true strength here.
The struggle that the Barcelona players did in winning over Villarreal in the continuation of the La Liga competition in Week 3 should be appreciated, they were able to show their quality as one of the teams to be reckoned with in the UCL. It must be admitted that Barcelona appearance in three official La Liga matches was not too impressive, they conceded three goals in the last match played even though they managed to win dramatically.
There is still something that needs to be improved in Barcelona appearance, their defense is still very fragile, the balance of the midfield is also not well coordinated. Lewandowski has just opened his goal coffers this season, the sharpness of the front line also needs to be improved to make it easier for them to break into the opponent's goal.
