I have some disappointments with the Barcelona players in this match. Barcelona should have won, but Yamal gave Dani Olmo several chances, but he couldn't finish them. Two good chances came his way, but Olmo seemed too hasty, shooting wide.
Further disappointment, I criticize the defense for being too ambitious, wanting to help the attack score while neglecting their own defense. Barcelona defenders often gave Rayo players chances, which almost resulted in goals. Hansi Flick must correct this performance.
To be candid on this, Rayo Vallecano should have been the team to win this very match and not Barcelona, Barcelona didn't create enough chances for themselves for you to be suggesting that they would have won won the game. Rayo Vallecano players were wastful and missed lots of chances to have been in front and eventually win the match. Barcelona keeper saved them, if not they would have picked the ball 5 times at least from their own net. 7 shots on target for the home side and 3 shots on target for Barcelona.
