Teenage Scottish winger Ben Doak has signed his first professional contract with Liverpool - five days after making his first-team debut.
Doak, who turned 17 on Friday, became the sixth youngest player to play for the club after coming on as a substitute against Derby County in the Carabao Cup two days earlier.
Following the 15-minute cameo in a tie won on penalties, the Scotland Under-21 international was also an unused substitute in Saturday's Premier League win over Southampton.
Doak joined Liverpool from Celtic this summer and the Anfield club say he earned his contract after "impressing with his quick, direct running on the right wing and eye for goal".
