I dont watch them unless they face strong opponents. But because I had Sensi on my fantasy team I kept track of when he plays and doesnt. He was rotation one and off for a while after getting back from injury, but since Aquilani was signed for regista role (Magnarelli injured for rest of season) he has been completely benched. And the b2b CM role is too competetive for Sensi, with Pellegrini doing well, Duncan coming back from injury to start, Mazzitelli gets more minutes then him too, and finally the formation chance that Di Franscesco makes at times with 4-2-3-1 to fit in Ragusa in midfield has not bode well for Sensi.
In general he had good chance to get minutes with Duncan, Missiroli, Magnarelli and Biondini all suffering long term injuries (2 of them still out cold, Missiroli about to play his first minutes of the season), but besides being injured himself at first, he has not taken the chance to establish himself in their absence. That honour goes to Pellegrini whos become key in their absence.
