It was the first game Barcelona played in a while as a team, Arsenal had played more, their players were sharper on the ball, and overall, Barcelona did not play poorly for their first game. Whenever I watch preseason games with all the changes that the coaches make to the team, I try to judge the performance of the team with their first and second half differently. Different players played in the first Half, and in the second half. The Barcelona players from the first half were not playing so well, they were able to score the first goal from a lucky rebound, and the second from a deflection from the defensive wall of Arsenal. The players in the second half played better, they were able to close down Saka better and create some good attacks of which one ended in a goal. Barcelona team will be stronger, they can win the UCL if they can fix some little errors in the team, or have a lucky run to the finals.
