Victory against Villarreal is very important to raise the morale of Barcelona players, because Villarreal is one of the strongest teams in La Liga.
I agree, this victory will improve the confidence of all Barcelona players. They will play more aggressively and optimistic in the next matches. This is a good sign for Barcelona management that the Barcelona team has promising progress managed by Xavi. It is probably too early to say this, but I saw some differences (changes) in Barcelona gameplay. Gradually, the real nature of Barcelona team returns, just look at how they control the ball possession in the last two matches.
It's true that Barcelona's way of playing has changed, now Barcelona is playing more confidently, and most importantly, teamwork is getting more solid.
I am optimistic that Xavi can bring back the glory of Barcelona, so I hope that in the next game Barcelona can win again. Moreover, Barcelona's next
opponent is Betis who are in a higher position, this means that this is a good opportunity for Barcelona to move up to a higher position. But Betis are
in 5th place now not by chance, this proves Betis a strong team, need a good strategy to beat Betis. But Barcelona have better quality players,
Xavi should have taken advantage of that and made Barcelona beat Betis.
