The clock is ticking before Manchester United step out at Old Trafford for their biggest game of the season.
With a place in the Europa League final at stake, opponents Roma have already touched down in the UK ahead of Thursday's first leg.
Of course, having seen neighbours Manchester City coast towards a third title in three years - in addition to United being knocked out of the FA Cup - the Europa League represents Ole Gunnar Solskjaer's only chance of silverware this season.
But can he replicate former United manager Jose Mourinho's European triumph from four years ago?
Here are five things we spotted from United's latest training session at their Carrington base;
Fun in goalkeepers' union
A changing of the guard between the posts at Old Trafford this season has been a serious matter; a huge decision for manager Solskjaer to make.
David de Gea has held the number one title for the best part of a decade, but over the last few weeks the Spanish stopper has been displaced by academy graduate Dean Henderson.

Of course, you could totally understand if there was a little tension between the pair - but far from it.
On the eve of United's biggest game of the season against Roma, which could see De Gea feature as he did in the previous round, the duo saw the funny side as one of the Carrington sprinklers turned on mid-session, forcing Lee Grant to dive out of the way and take evasive action.
Fortunately for Grant, Nathan Bishop was on hand to direct the sprinkler away from the group
Rashford fit to play

As things stand, United don't have many injury problems to contend with - although they are, once again, without the services of long-term absentee Phil Jones and Anthony Martial (both knee) against the Italians.
Marcus Rashford has, meanwhile, been playing through the pain barrier due to a troublesome ankle issue.
However, there is welcome news for Solskjaer ahead of kick-off on the selection front as the England forward took a full part in the squad's latest session at Carrington.
He was all smiles during the warm-up alongside Bruno Fernandes, too, as the duo were captured in conversation as they promptly took part in further fitness and ball-keeping drills.

Studious-looking Solskjaer
As he stepped out on to the training ground, the manager was not so much handed a guard of honour - but he did share a couple of light-hearted exchanges with United players.
Of course, all the while, he was donning that famous Solskjaer smile.
Once training began, though, the Norwegian took on a much more studious approach as he cast a keen eye on the simple warm-up drills that his squad were taken through at the start of the session.
He was even heard saying: "Right weight of pass," towards a high-quality group which included Fernandes, Rashford and the rarely used Donny van de Beek.
But will the Dutchman have impressed Solskjaer enough to be handed a start against the odds tonight?
Cards close to their chest
United have often used the Europa League to hand some of their fringe players an opportunity to impress, but you can't help but thinking it will be almost full-strength tonight.
Of course, the suggestion 'almost' depends on where you stand on the De Gea- Henderson goalkeeping debate.
While one can often glean information about line-ups or shape from training, Solskjaer and United's coaching staff kept their cards close to their chest on this occasion.
Indeed, first-choice players such as Aaron Wan-Bissaka and Fernandes were split into different groups, while a third team was headlined by Harry Maguire, Paul Pogba and Edinson Cavani.
Take from that what you will, but it would be a huge surprise to see any of those omitted from the line-up.
A glimpse into the future
The next generation of Old Trafford stars have continued their respective journeys during this Europa League push.
Indeed, the competition has seen the likes of Shola Shoretire (17), Amad (18) and Axel Tuanzebe (23) feature - while Anthony Elanga and Ethan Galbraith (both 19) are among those to have been included on the United bench.
Several of those players were involved here, many in 'team blue' alongside Wan-Bissaka as the entire United squad were put through their paces with a series of fitness drills.
