Erik ten Hag’s team will face the fellow Premier League club in the fifth round of the competition on Wednesday night, and we will know which side awaits the winner shortly before kick-off.
The last-eight draw is scheduled to be conducted from 19:00 GMT, 45 minutes before our game at the City Ground gets under way.
For viewers in the UK, the draw will be shown on ITV 4, as part of the build-up to Chelsea’s clash with Leeds at Stamford Bridge (19:30 GMT KO).
Meanwhile, Forest v United will be broadcast live on BBC One from The City Ground, where our all-time record goalscorer Wayne Rooney will be part of the TV studio line-up.
