The 21-year-old striker started the season well with two goals in the 4-0 opening day win against Chelsea at Old Trafford.
Solskjaer has been urging the young Mancunian to position himself between the posts before striking at goal, just as Ronaldo was coached to do under Sir Alex Ferguson.
Ronaldo bought into Ferguson and assistant coach Rene Meulensteen’s methods and improved his goal tally from 23 to 42 as United won the Premier League and Champions League in 2008.
Just as Ronaldo watched film of great United strikers like Ruud Van Nistelrooy, Andy Cole and Dwight Yorke, Rashford is studying Ronaldo to better understand how the Portuguese became so lethal in front of goal.
Rashford grew up watching Ronaldo alongside Wayne Rooney at United and recalled how exciting it was to watch them from the stands.
“When Ronaldo and Rooney were at their best, everyone wanted to be like them.” Rashford said.
“I was in the stands. I went to every home game since the age of six or seven.
“Ronaldo is the best I saw growing up and saw play live. He’s won five Ballon d’Ors and still has the determination and drive to improve. Most people don’t have that.
“Whenever people ask me if it’s Lionel Messi or Ronaldo, it’s always Ronaldo. Always.”
In 962 career appearances, Ronaldo has scored 689 goals at an average of 0.72 goals a game.
Rashford currently averages 0.27 goals a game.
