The question in this forum is rarely if we can be prime tiki-taka-Barcelona but if we play a dominant, active way or just counter attacking way of football.
Not sure if I merely misunderstand your point but there is definitely not a question whether we do actually play a dominant way. We don't. It wasn't there last season, it certainly wasn't there this season. But guess you meant the question is whether Bruno would be suited to the different approaches.
He obviously can. I think he could as well flourish, when he has a competent set of defenders and midfielders to build the play around him. Maybe not beeing that much on the focus but provide the team with sparkles when needed.
Well lets face it, your opinion is as good as anybodies on here. But there isn't much to bring more substance to either side - whether he would flourish in a possession heavier style or not. At this point, this isn't as much on Bruno himself, its on us - we haven't played or even attempted to play like that, so we simply don't know. International football isn't the greatest indicator though I agree, he looks a little more measured there as he did for us on a lot of occasions.
I maintain my doubts - possession heavy would mean forcing possession even in areas that are contested by the opponent. So not like Van Gaals United who were happy to play passes from one CB to the other but almost never move the ball in tighter areas. When it gets more tight, Bruno will have to find a way to deal with it, I wouldn't call him nimble or as having quick feet, he definitely doesn't have the upper body strength to make it work this way. Lets see, how things will go down. I guess, ETH certainly isn't the one to take us to some tiki-taka level, so his sort of dominance will probably always be pressing, forcing turnovers and situationally luring opposition teams onto us so we can create artificial counters. I certainly wouldn't say Bruno is unsuited to that.
