Manchester United will face Newcastle United in the Carabao Cup final on Sunday 26 February.
The game will kick off at Wembley at 16:30 GMT, and our Premier League clash with Brentford that day has therefore been postponed.
The EFL has also revealed that this will be the first major domestic English men's final in almost 35 years at which some spectators will be permitted to stand.

In these areas, supporters are allowed to safely stand in the allocated spaces behind a banner or a rail, which prevents them from falling forward. In all other areas of the ground, fans must remain seated.
Tickets for this area will be sold by the clubs, in accordance with the Wembley Stadium Ticket Policy.
