The Scottish midfielder has thrived at Napoli since joining the Serie A side last year - with stars such as Marcus Rashford and Rasmus Hojlund also impressing at their new teams - and thinks it comes down to confidence rather than the "myth" of it being hard to shine amid the pressure at United.

McTominay told CBS Sports: "It's just to easy of an excuse to say they left Man United and now they're doing well.

"Last year, I did well - I scored 10 goals and we won a trophy. With Marcus, there were obviously different issues that might have transpired which we won't go into, but Marcus is a top player and he's always been a top player. He's one of the club's legends, scored so many goals for Man United and done so many great things.

"Because the spotlight is directly on you, it makes it seem a lot worse in my opinion. Obviously when players go away and they're playing more games, they're going to have an increase in confidence, they're going to feel better about themselves than when you're playing less minutes at Man United.

"But when you are at Man United you have to earn those minutes, like Bruno Fernandes who's done incredible."

McTominay played a key role in Napoli's Serie A title win last season but will always be grateful to United for the role they had in his development as a player.

He said: "I just think it's too easy to blame Man United as a club because when I was there, they did everything for me.

"They helped me with nutrition, they helped me with training, they helped me tactically whoever the manager was there. Everything is put there to help you succeed. It's not like they don't do certain things that other clubs do.

"The myth of they go away and they're better players, it comes down to confidence. If you go away and you play every single game and score, you score again, and people start speaking, you feel good about yourself."
