9 man barca thrash sevilla 4 0 in la liga encounter
I think there may be a mistake here!
Barcelona has a traditional 4-3-3 formation, not 9-man. Additionally, it's highly unlikely that Barcelona would win 4-0 against Sevilla with only 9 players on the pitch!
Could you please provide more context or clarify what you meant by this statement? I'd be happy to help you with any questions or provide information on a specific La Liga match between Barcelona and Sevilla.
