Paul Pogba's recovery from an ankle injury has been compounded by illness, with Ole Gunnar Solskjaer suggesting it has set the Manchester United midfielder "back quite a bit".
Having fuelled speculation about his future during a summer of intense scrutiny, the 26-year-old has not featured since September due to an ankle injury that has restricted him to just six appearances this season.
United manager Solskjaer has spoken confidently about the Real Madrid target returning to action before the end of the year and Pogba had been due to resume first-team training this week, only to succumb to a new problem.
"Of all things he's struck down ill now," Solskjaer said on Sunday, when previewing the Carabao Cup quarter-final against Colchester.
"He's been off for two or three days – three days probably – so that's not beneficial. That's probably set him back quite a bit."
Solskjaer's comments came just hours before videos were posted on social media on Sunday evening, with Pogba dancing and showing few ill effects at his brother Florentin's wedding.
Mason Greenwood could well playing a starring role again on Wednesday, having followed up a brace and man-of-the-match display in the Europa League against AZ Alkmaar by hitting the leveller against Everton.
"He's making it hard for me to leave him out," Solskjaer said of the 18-year-old.
"I remember when I came to the club as well and I kept scoring a few goals but still I felt I could perform better, I'm not involved in the game, but the manager's comments were that it was hard to keep players who score out of the team.
"It's very, very difficult now to put a team out there without having Mason in my mind, yeah."
