A glimpse of United's next No.1?
It was nine years ago last month Dean Henderson entered through the doors of the United academy as a 14-year-old and tonight his quest to become the academy's only true goalkeeping success story begins.
Henderson is arguably the best 'keeper United have produced, despite the distinguished career Jimmy Rimmer went on to enjoy with Arsenal and Aston Villa after the returning Sir Matt Busby restored Alex Stepney. There are more England internationals next month and Henderson needs playing time in the League Cup this month to stay in Gareth Southgate's squad.
David de Gea was the only United starter who performed against Crystal Palace in what was an encouraging start to his season, despite the scoreline, which suggests Henderson has already jolted him.
How many changes?
United players looked fatigued before Crystal Palace scored in the seventh minute on Saturday and it would be senseless to start most of them. Aaron Wan-Bissaka, Eric Bailly, Nemanja Matic, Fred and Juan Mata could get minutes after they returned late to training and Donny van de Beek is in line to make his full debut after scoring at the weekend. For some, Luton could be a warm-up act for Brighton this weekend.
Another full debut?
With Victor Lindelof's approval ratings at their lowest since his calamitous outing at Huddersfield nearly three years ago, Solskjaer could end his Scandinavian solidarity and finally drop the Swede against Brighton. Bailly would be the obvious replacement but there is a wild card option in Teden Mengi.
Mengi, 18, came on for his career debut against LASK last month and sufficiently at impressed at Villa Park to draw praise from Solskjaer. With Axel Tuanzebe not match-fit, Marcos Rojo and Chris Smalling not under consideration and Phil Jones injured and irrelevant, starting Mengi would be logical.
Lingard in or out?
Given Jesse Lingard has been involved in every pre-season training session and started at Villa Park his exclusion from the weekend squad was ominous. Lingard's camp have encouraged speculation linking him with Tottenham but Jose Mourinho has no intention for moving for him.
Lingard's face no longer fits anymore and the player appears to have given up on recharging his United career. Starting him at Luton might only be an exercise in maintaining his resale value.
James to get a boost?
Solskjaer mismanaged Daniel James against Crystal Palace by switching him to the right when he had been productive from the left at Villa. James has looked much more comfortable cutting in from the left for most of his United career but was ineffectual on his weaker side and substituted at the pause.
Rather than dropping him, playing him from the left would address James' shaky confidence even if he is unlikely to line up at Brighton.
