Sevilla finished in fourth place for 3 consecutive years but not the best achievement unless Sevilla position can improve in the top 3 of the standings in the last 2 years, staying in 4th place in the standings for 3 years there is no improvement to be proud of but Sevilla must try more to achieve rank higher in La Liga next season.
For next season it looks like it will be even more difficult for Sevilla to reach a higher ranking in the final standings because teams like Real Madrid, Barcelona and Atletico Madrid will still dominate in the standings. Unless Barcelona really don't buy new players this season for a stronger preparation for next season, so Sevilla has a chance to perform better and occupy a better position in the final standings of La Liga.
Right now La Liga is no longer about Barcelona, Madrid and Atlético, the competition in La Liga has started to increase in the last 4 seasons and Sevilla, which used to be a mid-table team is slowly starting to become a team that disrupts the dominance of Barcelona, Atletico and Madrid at the top of the table, having some former players from great clubs makes now sevilla worth watching out for and I think next season they will also be a team that could put pressure on madrid and barcelona, this season it looks like sevilla haven't tried to bring in new players but that doesn't mean their not active in the transfer market, there are several names that may be released by sevilla such as martial and jules kounde but they are also eyeing several players to strengthen their squad next season.
