Blomqvist played a key role in United's Treble-winning season of 1998/99 and admires Young's ability to play as an "inverted winger" (on the opposite flank to his natural foot). But the ex-Red still thinks the former Aston Villa forward - who claimed an assist for England in the midweek defeat to Sweden - has more to offer.
"Ashley's a different kind of winger to what I was," Blomqvist told ManUtd.com.
"He's a right-footer playing on the left and that's not easy. I tried to play on the right a few times and always found it difficult. I never felt at home there.
"Ashley doesn't dribble past people on the outside as much as I used to but I think that's because he's playing on the opposite wing, which forces you to play a different style.
"I like him, though. He did well last season and now it's time for him to push on take the next step.
"Valencia, for example, keeps growing and growing – he seems to get stronger every time I see him. You can see he's improved a lot and developed his game since he arrived at the club."
