Oxford United play West Ham and Cardiff in pre-season
Oxford United will welcome Premier League side West Ham United to the Kassam Stadium as part of the U's pre-season build-up.
The newly-promoted Hammers have promised to send a full-strength squad to Oxford when they visit on 17 July.
Championship club Cardiff City will do likewise when they visit on August 4.
U's assistant manager Mickey Lewis told BBC Radio Oxford: "West Ham and Cardiff are big clubs, so these are exciting fixtures for supporters and players."
