He sounds like a real talent the way you describe him...I wonder why Chelsea dont want him, Norwich were unaffected by his genius, and why there isn't a long line of suitors for him?
The Chelsea lads on here, would say he needs to be a central focal point in terms of playmaking through the centre, Tuchal doesn't play that way, hes more functional in the engine room, with an athletic and defensive midfield for solidity and threat coming from his wingbacks, and midfielder covering, that's not Gilmour's game. But the lads would say he's very talented. Im not sure Chelsea dont wont him, he just doesn't fit at the moment, they extended his contract by year quite recently.
Ive heard conflicting reports on his time at Norwich, really the only outlet they had was Puki who was well flagged, the wide players came very deep and Puki often well marked and as the only outlet, in that sense you are holding the ball until the wide players join the play, as you say yourself he played the ball out side their a lot, but probably because it was the best thing to doo to hold possession. Im actually happy he got that experience at Norwich, not every year can be a CL winning year and he needed to experience life under the kosh and adversity. Dean Smith, is a bit of kick and rush merchant as well and the managerial change didn't help. If you look at it, other highly ratted young creative players struggled there last season like Dowel and Cantwell.
Im not sure there isnt a long line of suitors for them the above links says there are multiple PL teams interested in him taking him this season.
