I think we shouldn't expect any surprises today - the Catalans will try to go forward to the opponent's goal from the first seconds. The team has a very powerful offensive line, which will allow Barcelona to realize their chances. "Sevilla" now is not a team that can cause problems to the leaders of La Liga. So I think the Catalans will get three points.
Sevilla has tough defender Sergio Ramos even though he is no longer young but his experience against the Catalan team is no longer in doubt, even though Sevilla got off to a bad start to the season but in my opinion they will definitely put up a fight against Barcelona, even though Sevilla are not the favorites but I am sure that Sevilla being able to get points from at least a draw is far more enough for Sevilla, but if luck is on Sevilla's side then that is a bonus.
Sevilla has improved in performance when compared to the early days, yes it's not significant, but it's good enough. When comparing with Barcelona, it is clear that we will see a considerable difference between these two clubs, and it is natural that there will be many people who doubt Sevilla because they are dealing with a tough club, Barcelona. I also think Barcelona will win this game, but I wouldn't rule out Sevilla getting a point, at least 1 point in this game. Their defense will be really tested in this match, and it looks like Sevilla will play by relying on counterattacks and playing deeper.
