Alexis Sanchez is a doubt for Sunday's Manchester Derby after hobbling off clutching his thigh in the 2-1 victory over Juventus.
The Chilean was replaced by Marouane Fellaini with his side trailing to a Cristiano Ronaldo scorcher.
On paper, it will go down as yet another game without a goal for the former Arsenal star as he continues to adapt to life at his new club.
When he first signed, it was widely reported that he would be picking up a frankly obscene £500,000-a-week, money which so far, he has done little to justify.
So, what does Jose Mourinho see in him? Even the Portuguese is not perverse enough to continue with a player even if he can see that it's not working.
At the Allianz Stadium, Sanchez was once again thrust into the spotlight amidst the absence of Romelu Lukaku, with Mourinho having consistently made it clear he's reluctant to use Marcus Rashford in the middle of the front line.
The verdict? Well, the Daily Mail gave the 29-year-old a glowing review, praising his "game intelligence" - and his highlights reel shows the newspaper are pretty spot on:
Sanchez pressed high at times, but was also willing to drop deeper to drag Leonardo Bonucci out of position.
Sanchez's role is becoming better defined
The Mail's report explains:
"One of the criticisms aimed at £75milion Lukaku was his lack of hold-up play and aggression against defenders.
"Sanchez, the Premier League’s highest-paid player but one who has largely struggled since joining from Arsenal at the start of 2018, showed good technical ability, keeping the ball and bringing others into play, something that benefited Ashley Young, Paul Pogba, Ander Herrera and Anthony Martial in particular.
"His first touches found their intended target virtually every time."
The obvious counter-argument is that if Sanchez is leading the line, he ought to be chipping in with a few goals too, not simply keeping the ball creating chances for his team-mates.
However, in that light he actually played a key role in his side's attacking play.
It's just a pity United didn't reap the rewards of his toil until after he'd gone off.
