The Champions League will be more difficult than the European League, which requires Sevilla to prepare as well as possible so they don't become a team that only complements the Champions League.
Sevilla doesn't even need to prepare everything as it will always be going out from UCL easily. UCL has become a competition from best against the best. Sevilla was not the best in the liga. I consider sevilla was lucky enough in europa league as it was very often getting its goal from OG.
Sevilla was rarely winning against its opponent through free play. I would say that if UCL is still too far for sevilla to win it. It's caused by it will always become the competition for all of best clubs in the world.
The only team that can beat everything that will able to win it. Remember that the team like city can be considered as the best in the world right now.
They are a strong team in the Europa League, many even say they are the kings of the Europa League. They should be more motivated to become a team that is not only called strong in the European League, but also in the Champions League.
It doesn't matter a lot. Sevilla was strong in UEL but it's weak in UCL. Sevilla was always entering in UCL so many times but it's always going out from UCL when it was still in the group stage.
Winning europa league trophy is not enough to make sevilla will able to compete with the best clubs in the world.
It requires sevilla to perform better compared with the best club in the world right now.
