But who could be in-line for an opportunity at Boundary Park?
While Johnson is set to name a fairly strong side for the Papa John’s Trophy clash, there could be a number of fringe players and youngsters in-line for an opportunity.
Scroll down and click through the pages as we look at who could be given the chance to shine in Johnson’s second week in charge:
1. Anthony Patterson
Johnson has already confirmed that the under-23 stopper will be handed an opportunity to impress against Oldham - with the new head coach having heard good things about the academy graduate. Photo: Frank Reid
2. Dion Sanderson
Another player who Johnson has already confirmed will be involved, fans will watch on with interest given they have scarcely seen the Wolves loanee since his arrival on Wearside. Photo: Frank Reid
3. Jack Diamond
Diamond was introduced from the bench against Wigan on Saturday, but could be handed an opportunity to impress from the start in this cup clash - perhaps in one of the wide forward roles in Johnson's 4-3-3. Photo: Frank Reid
4. George Dobson
Dobson was arguably the standout performer in Sunderland's last game in this competition and, having been an unused substitute at the weekend, could get a start against Oldham. Photo: Frank Reid
