Wayne Rooney will be the star turn as he comes up against Manchester United tonight, the club he spent 13 years and scored 253 goals for between 2004 and 2017.
But his sole focus will be on his current side Derby County, as they look to cause the upset of the fifth round.
An away tie against Norwich City awaits the winner here, and you can find 27/10 for the Rams to qualify for the quarter finals.
Man United are 8/15 to extend their unbeaten away record to five games and progress to the last eight.
But with the Championship play-offs looking just a touch out of reach for Derby, they could really push United all the way.
A Rams win in Extra Time is 28/1, while the away side are 8/1 for victory in the same period.
Under Frank Lampard, Derby bagged a win over the Red Devils on penalties in the Carabao Cup last season. A repeat of this feat under new boss Phillip Cocu is priced at 14/1.
The home side should go full throttle at this with Cocu fielding his strongest possible XI. But will be without Tom Huddlestone, Duane Holmes and Krystian Bielik this evening.
They will be boosted by the return to fitness of Curtis Davis who should slot into defence alongside Andre Wisdom.
But all eyes will be on Rooney, who could be deployed as a number 10 or dictating things further back.
United could give Odion Ighalo a start alongside Mason Greenwood with one eye on the Manchester derby on Sunday.
Sergio Romero should continue in goal while Jesse Lingard and Juan Mata could be given a run out as Ole Gunnar Solskjaer hands Bruno Fernandes a rest.
Rooney to net against his former club is 7/2 anytime, with Tom Lawrence also at 7/2 to continue his purple patch in front of goal.
Chris Martin is 9/1 to break the deadlock for Derby, while the returning Davies is at 50s to score the opener.
Our traders have Ighalo at 21/20 anytime. While Greenwood is 5/4 to net tonight. Mata will be eager to impress and he’s 40/1 to score two or more.
