I heard he played more offensively in that match. I would be ok with this.
Yeah, for Roma's shape at present, maybe too offensively as it could probably be well described as a 2-1-7 at times.
Zeman is using Bradley so far solely as the left intermedio with usually Tachtsidis (or De Rossi tho it seems Zeman prefers him also in the intermedio more than regista) in the regista / holding role.
For Roma, where Totti is kind of a false winger since he often comes centrally to pick out runners, Bradley's role has been one touch passing in the quick build up and then making runs into the box in the final third.
His runs were very smart yesterday as he often was pulling defenders out of position to open up space for the strikers. His goal was the result of a run that pulled a defender off Destro who got a good strike on goal where Bradley finished the rebound.
The problem for Roma's shape right now is that we often have Bradley and Florenzi both in the box with both fullbacks fully committed forward and hence disaster if there's a turnover.
When the tactics work, like for Pescara last year, it should result in Bradley or Florenzi being in better position to press the ball high up the pitch to win it back but also with pretty risky gambling from the regista and central defenders helping out pressing extremely high up the pitch.
Under Zeman, he'll certainly develop his attacking runs and passing much more. Defensively it won't be the same solid, more traditional Italian emphasis on shape he was getting at Chievo.
