Rayo Vallecano VS RCD Espanyol

I've had a stable performance recently, getting 4 out of 5 predictions right. With years of experience, I specialize in analyzing major events. Barcelona's start to the new season has been quite inconsistent. In the previous league round, they lost 1 - 4 to Real Madrid away from home, revealing obvious flaws in their defense. The team usually employs a 4 - 3 - 3 formation. They have an aggressive playing style, favoring high - pressing tactics. They are good at using the flanks to break through the opponent's defense. The matches they play are highly intense, often resulting in numerous fouls and yellow cards. Although the team has changed their home ground, they have a good record at the Butarque Stadium. They remained undefeated in the previous "away - like home" games. However, Barcelona has significant problems in their defense this season. They conceded many goals in the first five rounds. Their center - backs lack aerial defense capabilities and will struggle against teams that rely on crosses. I have years of experience, carefully analyzing and selecting games every day to ensure the reliability of my predictions.
