Image source, Getty ImagesI don't think it is by accident Manchester United put their team news for the Grimsby cup tie on an X post with a massive picture of Kobbie Mainoo, external as the backdrop.
United know Mainoo is hugely popular. Any decision for him to leave would attract criticism from the club's supporters.
But the dilemma is clear. Mainoo has been picked in the Bruno Fernandes role.
If he is to get his place back, he has either got to oust the captain or persuade Ruben Amorim he can do another job.
Cam Gardner, who scored in the previous round, leads the attack for Grimsby. New signing Clarke Oduor is on the bench.
Grimsby XI: Pym, Sweeney, McJannet, Warren, Rodgers, McEachran, Green, Khouri, Vernam, Burns, Gardner.
Subs: Anton, Staunton, Amaluzor, Brown, Soonsup-Bell, Kabia, Turi, Oduor, Rose
There's a first start for Manchester United summer signing Benjamin Sesko.
In total, there are eight changes for the visitors, with Andre Onana starting in goal for the first time this season.
Man Utd XI: Onana, Fredricson, Maguire, Heaven, Dalot, Ugarte, Mainoo, Dorgu, Amad, Cunha, Sesko
Subs: Bayindir, Heaton, De Ligt, Leon, Casemiro, Fernandes, Mount, Mbeumo, Zirkzee.
There are four games involving Premier League sides in the Carabao Cup on Wednesday and BBC Sport will bring you every moment.

Image source, Getty ImagesBBC Senior Football Correspondent Sami Mokbel says Manchester United midfielder Kobbie Mainoo "needs to give serious consideration" to an exit from the club and risks becoming "the forgotten man" if he doesn't make the right move.
Mainoo seems to have slipped back quite a way since his 2023-24 breakthrough campaign under Erik ten Hag, when he scored in the FA Cup final and started for England in the Euro 2024 final.
After he was an unused substitute against Fulham on Sunday, Ruben Amorim said the 20-year-old is "fighting for the position now with Bruno [Fernandes]".
"If he's got to fight with the captain of the football club for his position, it doesn't bode well for Kobbie Mainoo," Mokbel told the Football Daily podcast.
"My understanding is that Mainoo reluctantly will consider offers going forward because I think he's realised his opportunities at Manchester United are going to be few and far between this season given his direct competition is the captain.
"I think there will be a lot of takers. Chelsea historically have an interest but they're pretty well-stocked in central midfield at the moment.
"In a World Cup year, for a guy who started in the Euro 2024 final for England, he needs to playing football and in my opinion needs to give serious consideration for an exit from United.
"He's maybe going to have to go down a rung lower on the Premier League ladder than he'd want to.
"I'd imagine for Kobbie Mainoo, as important as it is to play Premier League football, going down the food chain is fraught with concerns. If the step down doesn't go well, where do you go from there?
"Sometimes your career is governed by your transfers and what moves you take and if you don't make the right one you can very quickly become the forgotten man."
Image source, Getty ImagesWe asked for your views on whether Bruno Fernandes is playing out of position at Manchester United as his role was a discussion point on the latest episode of The Devils' Advocate.
Here are some of your comments:
Pete: United should have taken the money and sold him. He was the stand-out player in a poor team, but he is not a good enough standard for what they're trying to build. Bring Mainoo back into the side and buy someone to play alongside him.
Roger: Bruno Fernandes is definitely playing out of position. He should be playing further up the pitch behind the front three instead of Mason Mount and Mainoo should play where Bruno is playing now with either Ugarte or a new signing. That way we'd have stability in midfield and creativity, and Bruno in a more attacking position scoring or creating chances for goals.
Rahul: I think Bruno is a quality player. He is experienced enough to play in any position the manager wants him to. This thing about playing in only one position is overrated and seems only to apply to United.
Jon: Bruno being the captain is one of the main problems at United. Yes he is quite clearly the most talented player at the club but his attitude is abysmal - constantly moaning and throwing his hands up. Shouldn't have ever been given the armband in the first place.

Image source, Getty ImagesManchester United's Jadon Sancho and Chelsea's fellow winger Tyrique George find their futures strangely interlinked.
Sancho is Roma's first-choice target to strengthen their attack but multiple sources have suggested getting him out of Old Trafford is complicated.
One issue is his reported £300,000-a-week wages being an obstacle for any buying club, while sources in Italy also believe he is lukewarm about moving to the Serie A club.
Further complicating matters is United's ability to trigger an option to extend Sancho's contract for a further year, until 2027, to avoid him leaving for free after any loan deal should one be agreed.
Ultimately, talks between the three parties are complex, while Sancho's agent, Emeka Obasi, also works with Chelsea's George.
The 19-year-old has become a viable alternative for Roma, with Chelsea known to be open to a potential sale.
George is believed to welcome a move to the Stadio Olimpico and a source involved in the deal has explained that £25m should be enough to make it happen if a significant sell-on clause was included.
However, Sancho remains the first choice and any break in the impasse would be likely to result in Roma changing course back to the United man.
Chelsea have other interest in George in England and elsewhere in Europe.
Interestingly, the wingers played together last season at Chelsea and are known to have a close personal relationship.
Sancho is training in United's so-called 'bomb squad' away from the first-team group. George is training with Enzo Maresca's first team but was left out of the squad for Friday's trip to West Ham.
Chelsea are interested in United winger Alejandro Garnacho, Barcelona forward Fermin Lopez and RB Leipzig midfielder Xavi Simons before the transfer deadline next week.
Image source, Getty ImagesThe Devils' Advocate podcast's co-host Gaz Drinkwater criticised Ruben Amorim for playing Bruno Fernandes out of position in Manchester United's 1-1 draw with Fulham at the weekend.
The captain played in a more defensive role on Sunday, and also missed a chance to put his side ahead from the penalty spot.
Drinkwater said on the podcast: "Bruno Fernandes was United's worst player in the first half. This is not the Fernandes I know and love. And I think that comes from the position he's playing in. It's not his position."
Co-host Joe McGrath also questioned why the Portugal international wasn't sold in the summer: "The way Amorim plays means we can't get the best out of Fernandes. You scratch your head and think 'why didn't we just sell him for the £100m?'
"On his day, he's unbelievable. But if we're backing the manager and we can't get the most out of Fernandes but we can shift him for a great fee, what were the conversations that were had in the background?"
What do you think? Is Fernandes playing out of position? Should he have been sold in the summer?

Image source, Getty ImagesKobbie Mainoo leaving Manchester United is just the latest potential summer twist that no one could have fathomed a year ago. And with good reason.
Ruben Amorim has received incredible backing by the fanbase for a head coach with a 24% win rate in the Premier League.
But I can guarantee that the decision to offload an academy graduate of Mainoo's talent and potential would not go down well, especially if results don't improve.
This is a 20-year-midfielder who started for England in a major final around one year after making his senior debut.
Mainoo was talked about as a £100m-plus footballer. And that talk was justified, given his wealth of traits and early experience.
He has scored crucial goals against Wolves, Liverpool and Lyon, and the winner in an FA Cup final against Manchester City, no less.
The task of thwarting United captain Bruno Fernandes seems like an impossible and unreasonable one.
Fernandes will always be in the team, even if his disaster at Fulham extends into a poor run of form. So when will Mainoo's opportunity arrive?
You can't possibly tell me that Casemiro or Manuel Ugarte deserve prominent roles while Mainoo watches from the bench. United couldn't get any more hopeless in midfield.
When you possess a player of his quality, you find a way to make him fit. If that's not possible, then we have an issue with the system at Old Trafford, not the player. And, therefore, the head coach.
I was adamant Fernandes had to stay when Al-Hilal came knocking earlier in the summer. But who was I to know that it would be the 30-year-old or Mainoo at that stage?
If it saves the Stockport starlet's future and boosts the budget for a midfield arrival, I would swing the other way if the Saudi Arabia ship hasn't yet sailed.

Image source, Getty ImagesTalks are continuing around Rasmus Hojlund's potential move from Manchester United to Napoli.
Hojlund is not part of Ruben Amorim's 'bomb squad' but he has been left out of United's opening two Premier League games in the belief he will secure a move before the transfer window closes next Monday.
The Serie A side's manager, Antonio Conte, wants someone to replace Romelu Lukaku, who is facing four months out with a thigh problem.
I don't think the clubs are too far away on a price and while nothing has been signed off just yet, it does seem that of all United's various pending bits of transfer business, this deal is likely to be done first.

Image source, Getty ImagesManchester United boss Ruben Amorim is promising changes for Wednesday's EFL Cup trip to Grimsby, which means it is likely to be a big night for Kobbie Mainoo in particular.
There has been a lot of chatter about Mainoo, who is yet to feature for a minute in the Premier League so far this season.
Indeed, the 20-year-old has not started a game since the home defeat by West Ham on 11 May.
Amorim said after Sunday's draw at Fulham Mainoo was competing with skipper Bruno Fernandes in his line-up, which evidently is an issue for the youngster, deemed good enough to start for England by Gareth Southgate in the Euro 2024 final less than 15 months ago.
There is no suggestion of Mainoo agitating to leave United just now. However, talks over a contract extension have stalled and it is hard to see them resuming unless Mainoo can persuade Amorim he is either better than Fernandes, or can be effective in a different role.
Chances could be limited this season with no European distractions, so Grimsby needs to be the start of the process.
