Last night Barcelona managed to beat Osasuna very easily, I think this is very natural. Considering Barcelona's performance is very different from Osasuna's performance. So with this, it is natural that Barcelona was able to win easily in this match. In this match Barcelona was able to score 3 goals scored by Torres, Olmo, and Lewandowski. But unfortunately in this match Yamal did not score a goal, even though I really wanted to see Yamal score a goal in this match. But that's okay, because Yamal also played very well in this match and was able to make a full contribution to Barcelona's victory. So even though Yamal did not score a goal in this match, it can be said that he had an important role in this match. And with this victory Barcelona is currently able to lead 3 points over Real Madrid, I think this is an advantage for Barcelona to be able to continue to provide distance to Real Madrid.
I don't think Barcelona managed to beat Osasuna yesterday unless you didn't watch the game from the beginning till the end, because Barcelona scored 2 goals in the first half to lead Osasuna 2:0. I knew such victory will happen for the favour of Barcelona in this game despite the pressure of people saying that Osasuna players will not allow Barcelona to grab any opportunity in this game but they failed at the end for Barcelona to lead the game through out.
Despite he did not score goal from the game yesterday, but he contributed to the victory because they were able to beat Osasuna 3.0 to achieved 3 points.
