Greenwich, who sit third in the Isthmian Division One South, drew 1-1 against Walton Casuals on Tuesday evening thanks to a last minute Travis Gregory equaliser.
Sitting just two points behind leaders Lewes, the Boro will be keen to maintain pressure at the top. Elsewhere, the Rooks have a tough match against tenth-placed Thamesmead Town.
Recent history suggests Greenwich will have the clinical edge against Horsham this weekend, after Gary Alexander’s side completed an impressive double over the West Sussex based side last season; which included an exuberant 4-1 victory.
Both sides come into the clash in fairly inconsistent form, with the Boro struggling to pick up a winning run since easing past Ashford United, in a sensational 5-0 humbling earlier in the month.
Horsham will be keen to arrest their poor form, which has seen them ship six goals in their last two outings.
Plenty of options
Greenwich will have an array of attacking prowess to call upon, including former Brentford and Southend United hitman Charlie MacDonald, who has netted 12 times for the Boro so far this campaign.
Gregory is also available for selection as well as Jack Barham, who scored five goals in his first two matches, including a debut hat-trick against Ramsgate in October, for Boro.
A club with lofty ambitions, Greenwich’s fortunes have been on the up. The club’s newly established home at the DGS Stadium means that there’s a chance to build a fortress, and Alexander’s side will expect to make it a tough place to come for teams in the future.
