Jurgen Klinsmann admits Matt Miazga's transfer to Chelsea is massive for the USA.
The 20-year-old defender has joined the reigning Premier League champions for £3.5million from New York Red Bulls and US national team boss Klinsmann suggests a transfer such as this proves things in both his setup and that of Major League Soccer is working well.
"It's a huge move for him. Being 20 years of age, and now getting the opportunity to go overseas, and proving himself, is big," said the German.
"It's big I think for our program, it's big for us when a player moves to a Champions League team, a big team, a big club. We are happy for him, we are pleased, but we know also he is just developing.
"In the long run, he is a player that we're going to count on. He has showed already a lot of potential over the last two years, not only with [the U.S.] programs but with the Red Bulls, and now this is a big, big step.
"But we've got to be patient there. It will take time. He will go there to learn, and it will take time until he gets his chances there.
"It's courageous from Matt. It's a big opportunity, no doubt about it, so we are thrilled for him."
