The truth is hard to discern from this mess. I'm not inclined to believe anything the new Nantes coach says on this, so take it all with a big grain for now. The main thing at this point I think is that Miazga and Chelsea have 9 days to find him a good loan. He's 23, so the Chelsea academy is not a great place for him to spend the next 6 months, and there's probably no room for him on the senior team. Championship or Germany would be ideal, but opportunities for steady minutes are not easy to find this time of year.
