Louis Saha claims Marcus Rashford must be "more selfish" and improve his end product to avoid suffering the same frustrations as former Manchester United winger Nani.
Rashford, 24, has had a mixed season since returning from shoulder surgery with five goals and one assist in 18 games.
The England international came off the bench and netted a late winner against West Ham in January to score in back-to-back Premier League games for the first time since December 2020.
This served as an emphatic response to Red Devils interim manager Ralf Rangnick, who warned Rashford he must improve his consistency to force his way back into the starting XI.
Nonetheless, Saha shares Rangnick's concerns and fears the United academy graduate does not always "express" himself or have a lethal eye for goal.

The Frenchman likened Rashford to his former teammate Nani, whom he insists was "even more talented than Cristiano Ronaldo " in some areas, but crucially lacked a killer instinct and scored just 40 goals in 230 games for United.
"Rashford is an amazing player. What I like about him is he's very focused, he's not in the media for the wrong reasons," Saha told William Hill.
"But sometimes it's about his emotions. He does have emotion within himself, but he sometimes doesn't express it and so people get frustrated. He works hard… but he reminds me a little bit of Nani.
"Nani was even more talented than Cristiano Ronaldo in some ways - in terms of his physical qualities, he could run all day, physically he was so strong, skilful as well.
"But he was not deadly. He was not as deadly as Cristiano, who was very focused, knew how to score and when to score… And sometimes that's how I feel Marcus is, he's in-between.
"He has this potential where he can give a lot to the team, defend for the team, but he could be more selfish."
Saha acknowledges Rashford has shouldered a great burden since he burst onto the scene in 2016, but urged him to avoid Nani's trait of squandering "an opportunity that he shouldn't miss".
The 43-year-old added: "Nani was an immense talent for me, I loved the guy, but people were frustrated because he couldn’t find the right moment to make the difference, he'd miss an opportunity that he shouldn't miss, and sometimes that's what I see in Marcus.
"But Marcus started out at United very young and was asked to be the superstar and the one to save the club, so the education and the way he has had to protect himself since then has been difficult for him."
