The Matchweek 2 fixture was scheduled to take place at West Ham’s home ground, but due to the World Athletics Championships taking place at the London Stadium that weekend it has been reversed.
Instead, West Ham will host Southampton on Saturday 31 March. The date and time, currently 3pm for both matches, are subject to change.
