United's wonderkid, Alejandro Garnacho, is currently injured and watched the game at home.

A green 'Elux Legend 3500' vape could be seen on the sofa in the image.

It's unknown whether the vape belongs to Garnacho or not.

When will Alejandro Garnacho be back in action for Man Utd?

Garnacho suffered an injury during Man United's match against Southampton earlier this month.

Ten Hag noted that the injury was 'serious' but said he will be back before the end of the season.

"I can't say exactly (what the timescale is) at this moment but it will take weeks, so it's a serious injury," Ten Hag said, per Sky Sports.

"I didn't expect (that) but a foul, a serious injury once again after Christian Eriksen (after a tackle by Reading's Andy Carroll). We have a serious injury after contact.

"Of course it's difficult. He makes great progression and he was selected by the national team. It was a big moment for him and he's in a really good development and you don't want to disturb that process.

"Now we have to step away from it but he will be back for the end of the season.

"So, what he has to do now is deal with it, deal with the setback and then work, invest to get back before the end of the season because (at the) end of the season, we can win a lot. So, he has to be ready to get back as soon as possible."
