Van de Beek's chance to impress
Donny van de Beek has already caught the eye in his time at Manchester United but another strong showing from the start against Brighton could put him in contention to face Tottenham in the Premier League this weekend.
The £35million midfielder has been restricted to substitute appearances in the league so far, but against Crystal Palace and Brighton Paul Pogba has been withdrawn earlier and his patchy form must make a change a possibility this weekend.
Van de Beek scored in a cameo off the bench against Palace and impressed from the start against Luton Town in this competition eight days ago. This will be his second start for the club and given midfield is the area where United are strongest it feels like he is within touching distance of a Premier League start.
How Solskjaer uses Van de Beek remains interesting. He came on against Palace and played the advanced role and it's that position he will continue to operate in at the Amex Stadium, but he can drop into Pogba's deeper role, with Bruno Fernandes remaining as the playmaker.
Lingard or James?
The last week has been a good one for Jesse Lingard and there haven't been too many of those in the last 18 months or so for him at United.
With Andreas Pereira off to Lazio it looks like Lingard will remain at the club and he was something of a surprise starter at Kenilworth Road in the last round. The 27-year-old produced his best performance for a long time there and it was enough to see him on the bench in the Premier League at Brighton at the weekend.
It feels significant that his start in this competition and his spot on the bench came in the absence of Daniel James, who has been struggling for form of late.
Lingard does have versatility if he can regain confidence, able to play in the front three or in a midfield role, and this should be another opportunity for the academy graduate to try and continue working his way back into Ole Gunnar Solskjaer's plans.
The Carabao Cup is an opportunity at the moment for Dean Henderson and he took the chance to shine against Luton Town with a fine late save when the game was still delicately poised.
Henderson has to continue taking his chances in cup competitions, however. David de Gea has been pretty much faultless so far in the Premier League and while the expectation is that any mistakes the Spaniard makes will see the pressure increase, that won't be the case if Henderson makes any errors of his own.
He has to keep his slate clean in the chances he gets and these back-to-back Carabao Cup fixtures have been ideal to get him into the team and give him some early opportunities. He needs another solid performance.
It was a surprise to see Harry Maguire start at Luton last week. He was the only survivor from the first Premier League game of the season and looks almost undroppable at the moment.
At the time it looked like he was starting to lay the foundations for a partnership with Eric Bailly, but that proved not to be the case when the Senegal international was back on the bench in the Premier League this weekend.
Bailly will obviously start again, but Maguire is surely due a rest having started 61 times for club and country last season. His workload needs to be managed with three successive midweek Champions League fixtures coming up after the international break.
Solskjaer's cup record
United were within touching distance of three trophies last season but the semi-final exits in the Carabao Cup, FA Cup and Europa League only led to questions over their mentality rather than any medals.
But those defeats to Manchester City, Chelsea and Sevilla shouldn't overshadow Solskjaer's impressive cup record in charge of United. While he is still waiting to reach a final, results in knockout competitions have generally been good.
Another win on the south coast will continue Solskjaer's record of reaching the quarter-finals of every cup competition he's had in charge of United. If he can continue that run then a trophy cannot be far away.
