The Black Cats beat Sheffield Wednesday 2-1 on aggregate to reach the final, while Wycombe battled past MK Dons by the same scoreline over two legs.
Both sides set up with a 4-2-3-1 formation in the semi-finals but have also played with a back three this campaign.
For a bit of fun we’ve made a combined starting XI with players from both clubs.
