On their journey so far, Stockport County defeated Chesterfield FC as well as two Football League sides Rochdale AFC and Yeovil Town. On the other hand, West Ham United are set to feature in the FA Cup for the first time this season as Premier League and Championship sides enter the National competition.
The Hammers have struggled in the Cup since they left the Boleyn Ground in 2016. The East London club haven't made it past the fourth round, losing to lower league sides three years in a row.
David Moyes is expected to make a couple of changes to his starting XI for the FA Cup Third Round with a few players hoping for some needed minutes.
Ash Palmer is a doubt for the hosts picking up an injury last month.
Another player set to miss out on the FA Cup clash is Connor Jennings, picking up a knock before the Hatters played Altrincham early this week.
Stockport has revealed no other injuries ahead of the game.
West Ham United
Arthur Masuaku will be missed again as he starts his recovery after completing a successful knee operation.
Ryan Fredericks is also a doubt as he was tested positive for COVID-19 last week.
Lukasz Fabianski will miss the game with a thigh injury.
Stockport County: Hinchliffe; Southam-Hales, Hogan, Keane, Stott, Kitching; Croasdale, Maynard; Rooney; Reid, Bennett.
West Ham United: Randolph; Johnson, Alvez, Ogbonna, Longelo; Noble, Rice; Yarmolenko, Lanzini, Benrahma; Odubeko.
Ones to Watch
Stockport County - John Rooney
The attacker has been at the centre of the Hatters plans since the start to the season. Rooney has registered seven goals in 12 appearances in the National League.
In the Hatters' FA Cup run so far, the 30-year-old has scored four goals, scoring in each round of the competition. This includes a spectacular long-range effort against Rochdale, scoring from inside his own half to put the Hatters 1-0 up in the First Round.
West Ham United - Manuel Lanzini
The central attacking midfielder has been playing under David Moyes on the left side of the pitch. The Argentine has only scored once this season, however, hasn't had the opportunity to express himself. This cup game is the perfect chance for the midfielder.
Likely to start, Lanzini will look to create many opportunities and get on the score sheet for the Hammers.
