United's goal-laden march to the Milk Cup final continued on Thursday evening, as Paul McGuinness' young side hit another four goals to win a semi-final clash with Watford.
The Hornets were beaten 4-2 at Ballymena's Showgrounds, taking United's goal haul to a staggering 17 in just four games in the competition.
McGuinness' young charges now meet South Coast Bayern in Friday night's final (KO 20:15 BST), after the Americans overcame Hearts in a penalty shootout in Thursday's other semi-final.
United's 16-year-old Norwegian forward Joshua King scored twice in the last four tie, while Federico Macheda and Evandro Brandao grabbed the other goals to set up a place in the final of the prestigious youth tournament - now in its 25th year.
The Reds will be keen to avenge last year's final defeat to Brazilian side Fluminese, but United face tough opponents in South Coast Bayern, who knocked out the holders at the quarter final stages.
