I thought that initially, but the quotes Sky are running from the City source say it's a "huge embarrassment" so as funny as it is that everyone is talking about Stones rather than Pogba, we aren't exactly covering ourselves in glory.
I suspect City included Stones in the squad as it will definitely be completed and they want him to play in the qualifiers. City may have beem unaware when the UEFA website would upload the squad lists and were hoping to quietly finalise the details for Stones before announcing the signing either later today or tomorrow.
We'll probably need to announce this today now so not to let the saga drag on even further.
