We have, but we have always defended well in prior seasons.With done pretty well defensively as we are. Not sure changing the system is on the cards and I hope not but who knows.
But this season we brought in Dias which definitely helped too when we struggled a bit earlier.
I think this setup let's more natural defenders defend, and gives our forwards more freedom which benefits our attack, which hasn't been as good this season as last, because of how much we needed to improve defending. Don't expect any changes though, just my opinion of course.
