Bostock in: Three players who will hope to earn Nottingham Forest chance against Arsenal
The Reds have defeated Fleetwood Town and Derby County to reach this stage and face the Premier League giants in great form.
Boss Sabri Lamouchi has overseen nine unbeaten games in all competitions and he could utilise a rotation policy for the trip to the Emirates Stadium.
Several players will be chomping at the bit to earn a chance to impress the boss and it remains to be seen what changes will be made.
Here at Seat Pitch, we look at three players who could come in from the cold at Arsenal on Tuesday evening:
The 27-year-old was one of the standout players during the last round against Derby but hasn't played a minute of football since.
The defensive midfielder has been forced to play a watching brief following some sensational form by Ben Watson.
At 34, the in-form midfielder will probably get a rest for Tuesday night and that should open the door for Bostock.
The left-footer has looked neat and tidy when called upon so far and he will be desperate to stake his claim for a regular place against such a good side.
Another player who was tremendous in the Derby win was lively winger Adomah.
The 31-year-old has slipped out of the side since the last round of the cup, instead featuring more often than not from the subs' bench.
He's actually started life at the City Ground pretty well. He assisted Matty Cash's goal in the opening day defeat to West Brom and has helped himself to goals against Charlton, Preston and against Derby in the cup.
Adomah seems likely to come in on one of the flanks and he will hope to cause the Gunners problems with his pace.
The on-loan Benfica man has been in and out of the Forest team during the opening couple of months of the campaign.
He stepped off the bench to score the winner at Swansea City but was then made to settle for a place on the bench once more on Saturday.
Semedo showed his true quality in the last round of this competition and he will want to do the same at the Emirates if called upon.
