It’s not a good signal for those that considered Sevilla a trampoline to bigger clubs, only because Sevilla almost always played in an exotic fashion and were attacking-minded, which allowed players of all kinds to express themselves freely. I don’t mind us turning into a more solid side by defending better and playing tactically (also more robust like in the Emery days) as long as we keep winning and dominating teams.
However, as you and Edinho were saying, we shouldn’t rely on our luck too much and the 1-0 leads are always risky, hence we should go for more goals or at least make better use of our chances.
