Young defender Matt Miazga has explained his reasons for joining Chelsea during the January transfer window.

The USA international was a surprise arrival at Stamford Bridge, signing from MLS side New York Red Bulls.

Miazga said: "This is a great opportunity. My goal was always to go to Europe to test myself against the best players in the world and against top level opposition.

"This is the best league in the world so I'm looking forward to the higher level, getting better as a player and developing."
