The Youth Team bounced back from consecutive defeats to book a semi final place against Filton College after an impressive win against Bristol Telephpones.
Mangotsfield made a dream start playing some neat passing football to open up a three goal lead inside fifteen minutes to effectively kill off the tie.
The first came with five minutes played through Louis Ross, the second coming five minutes later, Jake Slocombe drilling the ball home from twenty yards.
A third from Lloyd Halliwell came on fifteen minutes as Mangotsfield continued to create chances against their Bristol Combination Division One opponents.
After going in three nil up at half time Mangotsfield created a number of chances in the second half before adding a fourth on the hour mark through Jack Withey.
Bristol Telephones scored a late consolation goal with five minutes remaining.
The semi final tie against Filton College is due to be played on Sunday 3rd March.
