They have both already made history this season – and on Saturday, two west London teams will be aiming to truly make it a year to remember.
Before this season, both Hanwell Town and Hanworth Villa had never made it beyond the third round of the FA Vase.
But Hanwell's 5-0 hammering of Lordswood last month, and Hanworth's impressive win at last year's finalists, Tunbridge Wells, put them both in the fourth round for the first time in their histories.
There, Spartan South Midlands League Premier title hopefuls Hanwell will host Ashford United, who in their previous guise as Ashford Town were long-time members of the Southern League and Isthmian League.
However, after going into administration three years ago, the club started again in the Kent League as Ashford United, and now ply their trade in the Southern Counties East Football League, which they lead this season, having lost just one game so far.
Combined Counties Premier side Hanworth, meanwhile, will host Eastbourne Borough, who currently play a level below them in Sussex County League Division Two, which like Ashford, they lead having lost just one game this season.
Also like Ashford, Eastbourne have known better times, having played in the Isthmian League up until 1991, since when their only bright spot has been a league and cup double success five years ago, but did not bring with it promotion back to the Isthmian League.
If they make it through on Saturday, Hanwell and Hanworth will go into the draw for the last 16 on Monday. Bill Healey, scorer of 39 goals already this season, will be Hanwell's key man, while Hanworth will hope Levi King can add to his tally of 14.
