I thought they would play a more active and offensive football after scoring 3 goals against Barcelona, but as you said, an early red card disrupted the concentration of the whole team. The game is almost over and they are down 3-1. The odds of a draw in this match are amazing. Cadiz is about to score an important three points.
A red card changes the course of the match, nothing miraculous happens because a team playing with only 10 players will create a gap that their opponents can maximize so that it is easier to beat them.
Villareal seemed to be trying to keep control of the ball and made more passes with better accuracy than Cadiz, but it didn't produce good results. Villarreal made substitutions after the red card but they only replaced forwards with forwards so gaps remained in their defence. This defeat was the second defeat in a row and the third this season.
It surprises me that cadiz is now placing at the 5th position. The red card was changing the tempo of this match. Im aware that if cadiz is only waiting for villareal to attack it first. Cadiz was just using counter attack to threatening villareal's goal keeper.
The cadiz defenders were doing its job perfectly. Villareal had been trying so hard to score the goals to make the scores to be the same, but it's failed. The goal keep of villareal did an unnecessary thing that was giving cadiz a penalty.
What a surprise result from cadiz. This club may be considered as a threat for the big clubs in la liga.
Celta Vigo finally got their first win after two previous consecutive defeats, and Almeria had to lose a lot of points in their home game, because of the three home games all ended in their defeat, there was no improvement in their game and it looks like they will again be fighting in the relegation zone like last season.
Almeria only got 1 point and it's now sitting above sevilal, which still got nothing from three matches. What you said above will be true if almeria will be once against battling for its place in the la liga.
This club potentially has to be relegated. No improvements happened to the almeria since last season.
