Sevilla will play in the Champions League as European League champions, and this will not be the same for Sevilla, and it is doubtful that they will be able to impress in providing tough resistance to their opponents later, especially if they are able to pass through the group phase, because the Champions League is more competitive because the best team in the league will compete for something prestigious, maybe if Sevilla make changes in the squad they will be able to compete more but with the current squad I doubt there will be a lot of things they can do, so like in the European league they are doubtful but able to answer doubts by lifting trophies but in the champions league everything will be very different. Sevilla must be willing to spend a lot of money to strengthen their squad but that is if they have it, because every club has different financial capabilities.
