I don't have a very positive expectation from the Cadiz - Sevilla match ahead truthfully.
Sevilla has now a brand new coach (Mendilibar) so chances are that your memories from the last match don't repeat. It is surprising how bad they have been playing, but nothing lasts forever, so I'm optimistic about their future performance and I hope they don't end suffering relegation, of course.
Be patient, dude.
I think that Sevilla must learn much from the previous matches. Moreover with that new coach, hopefully this will be much better (or not

)
But indeed the positions of Sevilla and Cadiz are not much different and they are both still inconsistent. Sometimes it's good, but often there are errors. Just look at how their match stats are in the last 5, it's pretty bad haha
But of course they will fight as hard as possible because this match is enough to determine their position later, whether there will be taken over or just left above it.
