I wouldn't be that cruel with Leicester. They've clearly focused on Champions League, and a smaller team like Seville could perfectly lose against them. Of course they won't get exploded, and we'll probably have a boring draw in Spain but a nice victory in England for the second match.
Sevilla is a smaller team? Dont try to make me laugh mate 
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.
