The Black Cats are on a fine run of form and are unbeaten in their last eight, but head coach Johnson will be forced into changes for the trip to Wembley.
Both Dion Sanderson and Carl Winchester will have to drop out the side after the win at Portsmouth due to being cup-tied, while Sunderland could welcome back a host of key players from injury.
The likes of Bailey Wright, Grant Leadbitter and Ross Stewart have returned to training this week – but would fans like to see them start at the national stadium?
We asked supporters what team they would name for the big game in a series of polls on our @sunechosafc Twitter account, and fans are calling for a pair of changes for the trip to Wembley:
1. GK: Lee Burge

2. RB: Max Power
The Sunderland skipper has impressed when he's been deployed as a full-back since the arrival of Johnson and could be asked to fulfil that role against at Wembley. 62.4% of those who voted believe he should play as part of the back four. Photo: Frank Reid
3. CB: Bailey Wright
With the Australian back in training, 49.5% of supporters want to see Wright return straight to the side against Tranmere. Photo: FRANK REID 2019
4. CB: Luke O'Nien
46.8% of supporters want to see O'Nien continue in the centre of defence - after he impressed against Portsmouth on Tuesday evening. Photo: FRANK REID 2019
