Matt Miazga insists he has no regrets joining Chelsea.
The Unites States defender spent last season at Vitesse, winning the Dutch Cup.
He said: "There's always that what-if factor, but at the end of the day I made the decision I made [to join Chelsea] and I'm glad that I'm doing it. "Everyone has their own journey. I'm on my journey right now, and I'm very happy with how it's going, my development as a person, as a player.
"I can't ask for anything better, and I'm very happy challenging myself in Europe at the next level."
