Miazga has suffered a lot in the past few months. His friend Emiliano Sala passed away and he endured a difficult situation during his loan spell.
He was accused of leaving the club without permission, but he denies any improper conduct during his loan spell in Ligue 1.
"It went well. I had a great time there, met a lot of good people, played good football. There was a managerial change, and then I was out of favour.
"This happens in football. You see it happen everywhere. It is what it is. I was lucky that Chelsea had the option to bring me back, then got out of one and into another. Chelsea knew it was best for me to get out of Nantes and go to a new club to contribute to my development.
"So, that's what happened with Reading. At Nantes, everything was fine and then finished off fine. I didn't like the way the coach said some things that were not true. That was absolutely false. It was not true.
"Everyone was aware that I was leaving, then when I was injured, we had a protocol to come to Chelsea. Everyone was aware of that, and you see it with many of the other loan players. Then Nantes, me and Chelsea agreed it was best for me to leave and go on loan somewhere else."
