Young Reds captain Glatzel scored twice in the opening 25 minutes of his maiden appearance at the first-team stadium to earn a 2-1 last-four win over Watford on Sunday.
A final against either Manchester City or West Bromwich Albion now awaits Glatzel and co, who are seeking to become the first Liverpool side since 2007 to lift the Youth Cup.
And the Liverpool-born striker, who has now scored 28 times in all competitions this season, spoke of the pride felt by Barry Lewtas’ squad following their victory.
