I think a draw from Barcelona is worth a win. Sevilla has been getting very bad results in the last matches and the average age is also quite high. When these factors come together, I do not expect them to have a fully productive season. Of course, they may get bad results this season, but they may also get surprising results. I think there is a small chance they can surprise the Barça match, but the more likely part is of course a Barça win.
Sevilla has started to play better in recent matches, and they are gradually rising in the standings. Average age is probably not the best comparison, since Barcelona has Yamal who is only 16 years old, this will affect the statistics, but I don’t really like such comparisons. Today it is important for Barcelona to win in order to get ahead of Girona and regain first place, and for Sevilla I think that even a draw will be good result, but their history of confrontations, especially at the Estalio Olimpico, is not in Seville’s favor. Barca still have more possession of the ball, but this does not give it a big advantage in game.
The match is still tied. Barcelona will take all the risks towards the end of the match because they will not want to lose points. Sevilla can score a goal if they evaluate the counter-attacks well towards the end of the match. If the match ends like this, it seems that they will not be able to beat Girona despite playing many matches and will give them the leadership.
