Sevilla FC. Are they declining?

Capitulated against Barca in such emphatic style is so untypical from them. And then eliminated from early stages of Champion league after hardly managed to arrive in fourth position of last season. Undelightful signing in the likes of cigarini, zokora, alexis, not the best player in their position I think. They seem never gonna able to change the key players with fabiano and kanoute in their 30s and Negredo always benched. I just see no continuity. And with Squillaci left for Arsenal, sevilla are always gonna be the seller club, aren't they? That's it, after hoping for Sevilla progression to become a real title contender, well there will be no "La Coruna" moment in the boring, boring La Liga (Real-Barcelona League) for the coming years.
