As a team, Sevilla has been winning consistently this season. Although there are also those who claim they play consistently poorly, it is less relevant when you're second in the standings. Sevilla should not blow the standing tables when they are in this situation, even if they are to be considered serious contenders. Especially when Real Madrid are at their best. Sevilla's title challenge has already passed the deadline.
The winning is not as important as the playing when it comes to consistency. This is a league and a marathon, so if you play badly and still end up winning consistently, it will come back to eat you up when the average scores round up. Playing well all the time (and getting Ocampos to be as fit as possible) will ensure they get over the line, because Real are vulnerable this season.
I agree of course, it's pretty much over in all the big leagues.
