To be fair, Gunnarsson is still on his way back from a long injury and may only be in the team thanks to Joe Ralls indiscretion; so it's surely not unreasonable that the medical staff are easing himself back into the full programme
As for Harry After, he has been one of the shining lights in the City team this season, so whatever Neil Warnock and his knowledgeable backroom team are doing, it seems to be working
I also agree that any further injury to Gunnarsson would be poorly received
