Rashford was handed his Manchester United debut by Louis Van Gaal in a Europa League round of 32 second leg tie against Midtjylland in February 2016, where he scored two goals to become the-then youngest ever scorer in European competition for the Red Devils.
The England international has since become one of the most important players at Old Trafford. Rashford was having a good 2019-2020 season, taking his personal goalscoring tally to 19 goals in his first 31 appearances before a back injury curtailed his season.
Darmian played alongside Rashford for four years before the Italian moved back to the Serie A in 2019.
The 30-year-old admitted he was impressed with the Manchester-born star during his time in England and insists Rashford has plenty of time to fulfil his full potential.
“I still remember Marcus Rashford’s first session with the senior squad like it was yesterday," the former Palermo and Torino full-back told The Guardian.
"I immediately thought: ‘Wow, this is an incredible player’. He did so many impressive things for a player of his age and the way he improved in every detail really impressed me.”
“If he continues to work the way he has done so far he can be a Ballon d’Or winner. I’m convinced of this. He impressed me the most of all the players at United and he’s very young and can still improve.”
"For me, he can reach the level of Kylian Mbappe and compete for the Ballon d’Or for years to come”
