Barcelona won the game against Valencia with huge scores but I believe Valencia lost because it made some mistakes which cost the club three points. The biggest error has come from its goalkeeper when he got a red card caused by handball. Valencia's goalkeeper was doing handball to keep Yamal from passing him when these two were one on one.
That is Valencia's biggest mistake. I'd rather let Yamal score so Valencia can score another goal with 11 players. That's a big mistake by Valencia's goalkeeper. He is suspended for several games following the red card.
The loss to Barcelona meant nothing because Valencia was not even at the bottom of the table. It only reduces Valencia's chances of participating in the conference league next season. I'm very disappointed with the outcome achieved by sevilla since it was missing opportunity after it leads with good scores.
Sevilla can draw against Barcelona as long as they play with 11 players. The red card became a key factor in Barcelona's comeback in the second half. This is the goalkeeper's biggest mistake.
I think Barcelona was very lucky to face Valencia with only 10 players and they were much more able to explore attacks from every angle so they could score more goals. It is proven that Lewandowski recorded a hat trick and that is why it will be very difficult to stop him if there is empty space in the defense.
