The 20-year-old US international centre-back has made the matchday squad for Chelsea's past two games.
Viewed as a long-term project, the US international centre-back has not made an appearance for the Premier League club yet, but Blues manager Guus Hiddink recently revealed that he was “close” to earning playing time after impressing in training.
In the meantime, the 6ft 3in defender has been an unused substitute for the last two games against Paris Saint-Germain and Manchester City, respectively, and Klinsmann is looking forward to closely monitoring his progresses at Stamford Bridge over the coming months.
Asked about his thoughts on Miazga’s move during a Facebook Q&A before last night’s Copa America Centenario draw, Klinsmann said: “Having Matt in this very, very competitive environment at Chelsea will make him only grow. It will make mature even faster and he’s a very talented young player.
“He’s obviously physically very strong, but now he will have to learn all the little things there at such a big club like Chelsea, so hopefully he will adjust over the next couple of months.
“Right now he’s clearly in the picture for our Olympic team, but it’s exciting to see him being on the bench with Chelsea.”
Miazga originally joined the Red Bulls academy in 2009 before signing a Homegrown Player contract with his hometown team in 2013 after rising through the development ranks.
The New Jersey native, who holds a Polish passport by way of his parents, featured just eight times for the club during his first two seasons in MLS but established himself as a regular starter last term, making 30 league appearances while helping Jesse Marsch’s men win the Supporters’ Shield.
His promising performances earned him his international debut as a second-half substitute in November’s opening World Cup qualifier against Saint Vincent and the Grenadines, before he was later named US Soccer’s Young Male Player of the Year in December.
Since moving on to Chelsea, it remains to be seen how much first-team action the one-time capped American will see over the rest of this season or if he will be sent out on loan next term, but if his rapid progress during the last 12 months is anything to go by, his future with the Blues should certainly be bright.
