Former Manchester United midfielder Ander Herrera has backed Marcus Rashford to become a legend at the club.
Herrera registered 20 goals and 27 assists for Manchester United before leaving the club in 2019 to join Paris Saint-Germain.
The 33-year-old, who has since returned to his boyhood club Athletic Bilbao, claimed in a recent interview that his former United teammate can become a club legend.
Herrera told ESPN: "Marcus makes a big difference when he's fit and when he's in a good moment – and he has now the best teacher in the team, with the best example, with Cristiano.
"So, of course [he can be a key player], but sometimes we are not fair with some players. We are not fair with Marcus or – I could give you more examples – with Vinicius [Junior] or with these kind of players.
"You cannot compare them with [Lionel] Messi and Cristiano because it's like if the Spanish midfielders, we are compared with Xavi [Hernandez] and [Andres] Iniesta. We are going to lose [that comparison], of course.
"Marcus has everything to become one of the biggest Manchester United players in history. He is back at his best, he is scoring and helping the team and as a United fan I'm happy."
Rashford has enjoyed a successful start to the season, scoring three goals and two assists in nine top-flight games, while also winning the Premier League player of the month for September.
The 24-year-old could next be in action when Manchester United face Tottenham Hotspur at Old Trafford on Wednesday.
