This is a trash take on so many levels.
For starters, if you don't think Dome "implemented his own tactics," what team were you even watching? We switched to a new formation in his very first game. We cycled through interesting variations on the 4-2-3-1, 4-3-3, and 4-4-2 diamond as he adjusted to opponents and his available squad. He tried players in new positions. He even tried positions in new positions. This was in no way a continuation of Vieira's tactics, as some people on this forum have contended, and it certainly wasn't a copy of Manchester City. It was a tactically astute coach working to make the most of what he was given. Whether or not you think he succeeded, at least pay attention to what he did.
As for taking cues from other coaches, how the hell do you think tactics develop? Do you think people just sit around in a dark room dreaming up new ways to play soccer? Guardiola learned from Cruyff and Bielsa. Vieira learned, sort of, from an earlier iteration of Guardiola. Now Torrent is trying to catch the team up with what's been going on in Europe for the last five years. Of course he's relying on the genius of others. That's what coaches do.
And don't even get me started on that parenthetical. If you're not sure whether Guardiola's a good soccer coach, honestly man, just find another sport. This one's not for you.
