The City boss pulled no punches when he was asked directly in his post-match briefing whether Tettey's removal from the starting line-up was due to a reported training ground altercation.
"No. Listen I can tell you categorically now that isn't the case, but can I say that is a naughty question," he said.
"It has been a good day. I don't know where you have pulled that one from because the spirit is incredibly good. We have an excellent group of lads. It would be difficult for there to have been a training ground incident when he didn't train, so that is a little bit naughty.
"He had a slight knock. Alex felt something a couple of days ago. The good news for us is its minimal. It is one I could have played him today but that is the balance sometimes as a manager. If I had, he could have been fine or it could have been something that was made worse and with the competition we have at the minute I decided to leave him out and certainly not to aggravate it."
