Oh so you ignored the rest, good stuff, another Davek.
So you're happy with being called small time by the manager who brought us to the level we are at, putting in cheeky sly bids for our best players and telling them that Everton (which he was managing up until a month ago) are not a good enough team for them? Good, nice, David Moyes FC style logic.
First off, "they're both defensive managers", but it seems all of your education was in football intelligence. No idea why you'd bring up Simeone in this, hilarious to think you equate all 3 in the same bracket and just shows you've not even seen any Atletico Madrid games that haven't been against Real or Barca. Then again, you're the football intelligence megamind, so what does anyone else know, right?
Dyche and Moyes are cut from the same cloth, however Moyes moved past "proper brexit 4-4-2" when he had to, 20 years ago, whereas Dyche never did and never will. The rest - stubbornness, overly-defensive setup and attitude, putting down your own chances, knife to a gunfight, stereotypical signings ("big man up top") - are 90% the same. The other 10% are from Moyes actually managing games better than Dyche, but that's a hilariously low bar.
Dyche is closer to Moyes than you seem to think, Mr. Football Intelligence PhD, and replacing one with the other will be a slight improvement at absolute best and a detriment to any growth for another year or two. Sit with Dyche until the end of the year for stability - okay, sure. Then bring Moyes back in for... stability again? OK.
