Off the back of Wednesday's 3-0 win against Derby County, Thomas Frank's side head East to take on The Hammers, kick-off 2pm. A link to watch the game live will appear on brentfordfc.com shortly before kick-off.
David Moyes’ side finished last season 16th in the Premier League, five points above the drop zone. United lost just one of their last seven league matches, taking 12 points from that run, to ensure they remained a top-flight side.
This will be West Ham's third pre-season outing after playing a pair of friendlies simultaneously on Tuesday afternoon. While a Sebastien Haller hat-trick and a Tomas Soucek header was seeing off Ipswich Town at Portman Road, Jarrod Bowen scored twice, while Arthur Masuaku and Manuel Lanzini were both on target in a 5-1 win over Wycombe Wanderers at Adams Park.
Less than 24 hours later, Thomas Frank's side got our pre-season off to a winning start against The Rams; Marcus Forss, Christian Norgaard, and Mathias Jensen on target at St George's Park.
As well as a live stream on brentfordfc.com there will be full social media coverage of tomorrow afternoon's match from noon.
