Aye he's been decent since he's been brought back into the fold in that formation, and I think it's unfair to say he can only play against no-hopers such as Norwich at OT. Good against Burnley for me and transformative against an admittedly more conservative City side in the second half does not indicate a player who is utterly finished, the trouble is as you say he offers nothing outside of playing at the base of a midfield three. His legs, which are only going to get worse, and his lack of positional versatility mean he's on borrowed time here but he's at least managed to prove he can be useful this season, which I and many others had believed was beyond him.
