Manchester United's Champions League Return: Defensive Concerns Loom

Manchester United’s return to the Champions League should feel like a celebration. Instead, it comes with a familiar sense of unease down the left.

Nearly three years after they last kicked a ball in this competition, United step back onto Europe’s biggest stage tonight against Sabah FK. The club that once treated Champions League nights as routine is back after a turbulent spell, their last appearance ending in humiliation with a group-stage exit in 2023 and a bottom-placed finish under Erik ten Hag in the 2023/24 campaign.

The landscape has changed since then. The Champions League format has been revamped, 36 teams thrown into a single league table. For Michael Carrick’s United, finishing anywhere near the bottom this time would signal a crisis of a very different kind.

And that’s where the team sheet becomes a story of its own.

Defensive doubts and a familiar problem

Senne Lammens will start in goal, a straightforward call in a side where very little else at the back feels settled. United’s defence has leaked too many chances already this season, and this competition is unforgiving to teams that defend on reputation rather than structure.

Diogo Dalot is likely to keep his place on the right, but the real intrigue lies in the centre. Leny Yoro could come in alongside Harry Maguire, a pairing that would nudge Lisandro Martinez out of the firing line. Martinez has looked rusty, short of his usual sharpness, and with the Manchester derby looming this weekend, Carrick has every reason to protect him now to get him right for City.

Then comes the problem United saw coming but never properly solved: left-back.

All eyes will be on that position when the team news drops. Luke Shaw did not train on Wednesday. Carrick insisted there were no injury concerns, describing it as a rest day, but with such a quick turnaround before the derby, that almost certainly rules Shaw out of tonight’s game. United gambled in the transfer window by not strengthening there. That decision is already creaking under pressure.

Harry Amass did train, but throwing a youngster into a Champions League return is a huge call. Patrick Dorgu offers another option, yet his qualities make more sense higher up the pitch. So the most logical solution is a compromise: Noussair Mazraoui shifting across to cover on the left, a right-back asked to patch up a problem area once again.

For a club of United’s size, it is a familiar, uncomfortable workaround.

Balance in midfield, calculation in attack

The picture in midfield is clearer. Kobbie Mainoo will start, the youngster now a central pillar of this side rather than a promising extra. Youri Tielemans looks set to partner him again, offering control and experience alongside Mainoo’s energy and press resistance.

Ahead of them there is no debate. Bruno Fernandes is still the first name on the teamsheet, the creative hub in the advanced role, the player United rely on to turn possession into chances on nights like this.

Up front, the decisions are shaped by Sunday as much as tonight.

Benjamin Sesko’s minutes are being carefully managed and with the Manchester derby on the horizon, it would be a major risk to start him and potentially rule him out of the City game. United cannot afford to burn him out now and pay for it at the weekend.

So Matheus Cunha is expected to lead the line, a centre-forward tasked with linking play and dragging defenders around rather than simply finishing moves. Bryan Mbeumo and Marcus Rashford should offer the support from wide, two players who can stretch the pitch and attack space behind Sabah’s back line.

On paper, it is a side strong enough to handle this opening test. But the margin for error in this new Champions League format is thin, and United know too well how quickly a campaign can unravel.

They are back in the competition they believe they belong in. The question is whether an unresolved left-back problem and a defence still searching for solidity will let them stay there long enough to matter.
