Chelsea loanee Mason Mount scored once in Derby County's 2-0 win over Oldham in the first round of the Carabao Cup.
Sam Graham grabbed the opener for Frank Lampard's side in the first-half, before Mount doubled the advantage in the second stanza.
The 19-year-old lashed home a beautifully timed half-volley after 70 minutes to grab his first goal for the Rams.
Mount displayed his immense potential during a loan spell with Vitesse Arnhem last season, in which he scored nine goals in 29 appearances.
Chelsea are hoping the Englishman will learn under Blues legend Lampard.
