We have been seeing improvements in Barcelona for a few weeks. I do not expect them to beat Atletico Madrid so easily, but they were very good and did not play a great match. An important moment in the match was when Xavi was suspended due to his objections. This was an important moment.
Even if Barcelona was ahead, the players could have been affected by this situation, but that was not the case at all, on the contrary, they scored two more goals and Barcelona beat Atletico Madrid 3-0 today. Barcelona's young players show a lot of promise: Yamal and Pau Cubarsi
If you have been notice Barcelona impressive performance was happened since Xavi decide to withdraw from his current position as a manager in January because since that month Barcelona has successfully to improved their performance significantly and still unbeatable in all competitions with gets 7 wins from 10 marches even currently Barcelona can able to taking over second place from Girona and i wouldn't talking about race title between Barcelona and Real Madrid because obviously Real Madrid is too consistent compared to Barcelona but if they can able to managed their position at least Barcelona can finish at runner up place at the end of this season
About the match against Atletico Madrid honestly before this match begin i am the one who doubt Barcelona can able to overcomes Atletico Madrid because previously it is hard to beat Atletico Madrid at their home ground but apparently i was wrong because Barcelona has displayed fantastic performance in this match and win with big scores 3-0 and as far i know this is the first time for Atletico Madrid lost with 3 goals margin this season in Laliga but unfortunately Barcelona have to lost Xavi because he was received a red card and he will be absense when Barcelona met Las Palmas
