Miazga, aged 20, joined the Red Bulls’ academy as a 14-year-old in 2009.

His old club hunted out a profile book from Miazga’s first season with them and shared his photo from it via their Instagram account.

They also look the opportunity to wish the young centre-back good luck following his £3.5m transfer to Stamford Bridge.
