Most probably yes. It will depend on the current use of the land (i.e. if it's agricultural currently then you will need permission for change of use), the specifics of the court (i.e. will it have lighting? will it have high fences?) and if the location is in the green belt.
There's a guide that might be handy at https://www.sportengland.org/how-we-can-help/facilities-and-planning/planning-for-sport/sports-club-planning-application-guide
if i buy a field and want to put a court on it (MUGA or otherwise) do i need planning permission? i'm looking at eg https://www.planningportal.co.uk/permission but input very much appreciated
