Strikes from Nathan Davies, Jack Mattey and Alex Rose steered London Lions under-15 Whites into the final of the Watford Friendly League Cup following a 3-1 win over Evergreen Youth.
Evergreen forged ahead after 25 minutes when a sweetly-struck shot looped over Jack Rifkin.
Lions equalised three minutes later when a sweeping move involving Sam Hamerton, Max Misrahi, George Leigh and Ethan Novak allowed Davies to apply the finishing touch.
The Lions gained the upper hand five minutes later when the industrious Jack Mattey beat two players before lashing home to give the hosts a 2-1 lead at the break.
The Lions dominated the second half, playing with more intensity and control. Rose added a third following a precision pass from Mattey.
Evergreen were denied by the woodwork in the closing stages, but the Lions held firm, with substitutes Alex Randall and Ben Feldman, along with Jordan Green, Ollie Light, Aiden Raphael, Nathan Anders Jordan Green and Ben Lazarus in commanding form.
Lions coach Darren Yarlett said: "I have faith that the majority of this squad can represent the club in Saturday football and Maccabiahs in future years.
"This is both mine and the club's aim and we will get there, but patience will be needed to succeed.
"A large chunk makes up both the Team MGB futsal and football squads for Berlin which speaks volumes for the boys and the hard work that managers Mark Rose and Darryl Lazarus have done."
