Jose Mourinho’s side travel to Turin in the Champions League looking to avenge a 1-0 defeat in the reverse fixture two weeks ago.
Ronaldo featured in the clash at Old Trafford and will be hoping to bag his first European goal for his new club against his former employers tonight.
The Portuguese enjoyed six successful years in England, winning three Premier League titles and one Champions League.
Rashford grew up supporting United and sees Ronaldo as one of his childhood heroes.
“You can’t show fear to that type of player.”Man Utd star Marcus Rashford.
But while the 21-year-old has a lot of admiration for the superstar, he will not let the occasion of playing against him be a distraction.
“The thing that is a massive eye-opener for me now is I remember when he first came his talent was arguably one of the biggest talents that we’ve seen at United for a long time,” he said.
“To have him and Wayne [Rooney] in the same team was amazing when you look back.
“But the way he’s sustained his career and even improved year on year is just amazing.
“People don’t do that at his age, people are usually heading towards the end of their career and their level starts going down a little bit.
“But he’s just gone up and up and up. For me, there is no bigger inspiration in football.
“I could speak for a lot of young players and United fans that watched the team when he was here and the majority of us have followed him as he’s moved on in his career and that’s what’s special about United.
“Once you play for this club you become part of this family even if you move on.”
True the Red Devils have a tendency to give a player that feeling.
