Di Matteo had just taken over as interim Head Coach at Chelsea following the departure of André Villas-Boas. In his short time as assistant manager at Chelsea he has won the UEFA Champions League and FA Cup. He currently helps to oversee the progress of Chelsea's loan players after having been assistant first team coach under Guus Hiddink in for the second half of the previous season. Following the departure of Hiddink, Newton returned to the loan technical coach role until 2019, when he became an assistant coach to the first team following the appointment of Frank Lampard as head coach.
