There are only two games tomorrow and Real Madrid - Betis looks like the most impressive one. Actually Real Madrid are just playing for ending the season now but we still can't know how much willing they would be to become the winner of this game. But I feel confident about one thing that is they would rotate their starting eleven a little. We will see if Betis will be able to take advantage of it. They might still lose one place in the league table and they had better get one point in the worst case. It's not impossible but it's quite difficult too.
I'm pretty sure even if real madrid plays with their second team , they are strong still.
Moreover real betis need to win this one very badly to keep their chance to play at the champions league next season alive , sevilla at the 4th spot will play against bilbao which could be a slip of the season and betis could get that spot if only they beat real madrid which pretty much possible !
