Perfectly. Sevilla is first not concentrating on Champions League like Leicester is doing. Budget is also not the same, Leicester's one being quite largely superior. Finally, I believe Leicester players to be better. Just Vardy is better than Nasri. Mahrez is also an excellent player.
So the team that concentrating to Champions League too much means they are a big team? Not sure where you get that logic. Sevilla is the most successful team in Europa League, and in otherwise its the first time to Leicester playing in european competition.
