What I said, just because Roberto Martinez didn't win the title with it doesn't make his implementation inferior to that of Conte's, even if it's obviously Conte is a much better manager than he is. You can't expect Wigan to win the league no matter what formation they play.

Popularization is the keyword here, Conte won media admiration only because he managed to win the league with it, no one would've bat an eyelid if he didn't. Hypothetically speaking if Conte had used it to save West Brom from relegation for example like Martinez did with Wigan, it would still be an achievement because of how shit those teams are, but it wouldn't have caught as much media attention even if they were successful with it.

And there really aren't that many teams who are using it. In fact, I would say only Wenger's Arsenal were the only other PL team who were using it regularly as their main formation. Spurs uses it sparingly often rotating between 3 and 4 at the back.
