My prediction is that Villareal will lose to Barcelona and Bilbao will win against Sevilla. All teams will give a good game at the close of this season. I will not feel guilty if Bilbao will be the Team that will compete in the European Conference league qualification. And in another match between Cadiz and Alaves I will bet on Cadiz win and Cadiz deserves to stay in Laliga for next season.
There are some matches that are most decisive for some of the teams who still have a chance to qualify for the Europa League, European Conference League or Champions League. Maybe it will still be interesting to watch this weekend even though we know that Real Madrid already has the title.
Some of the interesting matches are:
Barcelona vs Villareal
Real Madrid vs Real Betis.
Sevilla vs Ath Bilbao.
In my opinion, all the home teams in the matches I mentioned would probably win. But anything can still happen because some of them are still concerned with winning.
