The Red Devils are back in the swing of domestic action after the World Cup, beating Burnley in the League Cup on Wednesday night.
They return to Premier League action on 27 December when they welcome Nottingham Forest to Old Trafford, but McTominay has had to face some unwelcome questions ahead of that.
Responded to the clip of him and the Argentine winger McTominay told The Athletic: ‘I had a lot of people saying that was bullying. That was just a bit of a joke!’
However, he did offer some advice to Garnacho, who has had some criticism from his Manchester United teammates in his young career so far.
‘He needs to keep his feet on the ground and keep working hard and he can be one hell of a footballer,’ said McTominay.
He added: ‘I’ve never been interested in, if things are going wrong — and I’m not saying I’ve had that here, but I have experienced it over my time in football, when I was a kid — speaking behind people’s backs if you don’t win. That is just a disaster.
‘You need players in the group who are straight-talking, say things to people’s faces, and if they like it they like it, if they don’t they’ll get over it next week.
‘I feel like we have a really good group for that, especially with the lads who are playing every week.’
In November, Bruno Fernadnes made quite a surprising revelation about Garnacho, calling him out publicly on his poor attitude and why it took him a while to break into the first team.
‘At the beginning of the season he was not at his best. In the [pre-season] tour he didn’t have the best attitude that he should have, and that’s why he didn’t get his chances until now,’ said the Portuguese star.
‘He’s getting his chances because he’s training better, he’s got a different attitude and he’s deserving his chances.’
