Today I watched the highlights of the game and yes, Granada looked very good, but what kind of strength are you talking about? The team is in 19th place and has 13 points from 24 games. This is the obvious outsider. The problem is Barcelona - they have a terrible defense (Granada could have scored more) and against its background even teams like Granada look dangerous.
You can be 95% sure that Athletic will win against Almeria today (the team has 6 points and 17 defeats lol) and so it turns out that we will have an interesting fight for the top 4 where Barcelona will not be safe at all.
Before now, Barcelona were regarded as one of the strongest teams not just in the Spanish La Liga but also in the UEFA Champions League competition and were feared by the smaller clubs but since they started underperforming, almost all the clubs that are facing does not see that fear factor in them again and now believes that Barcelona are very much beatable.
The 3:3 draw between Granada and Barcelona yesterday is a prove that the claims .of the club manager Xavi Hernandez are true. The Spanish manager last month said that things have gone too bad at the club and that it'll be very difficult to maintain the club again hence his decision to leave the club at the end of the current season. Barcelona are currently in the third position of the league table but if they continue with their current performance, they might not finish the season in the top four of the league table
I think La Liga teams are not initially afraid of Barcelona in the same way that clubs from other countries which play with Barcelona very rarely are afraid of it. Why are they afraid if they play with this club at least 2 times a year? In this case, it is perceived as routine, especially against the backdrop of the fact that there is also Real Madrid. It's just that Barcelona is weak now and it's easy to take points away from them.
As for the fight for 4th place, unfortunately Athletic unexpectedly played a goalless draw and now Barcelona has a margin of 5 points to feel calm. But it is far from certain that they will retain this reserve.
Barcelona is really bad this year. Needless to say more, they are bad. Because they are bad, even low ranked teams can get points from them. It was a miracle to get points from Messi when they played with him. Now it's an ordinary thing. We have seen how variable a player can be for his team. Barcelona was never the same after Messi left. Xavi's method is no longer valid this year.
