By the way...
Do you remember how shit Rooney was in 2010/11 in terms of scoring goals? He scored 16 goals anyway. A number that Rashford hasn't matched yet.
Rooney and Rashford were both born in October. So comparisons by year should be fairly linear.
By this point in Rooney's career (21 years and 3 months, after 22 games played in the PL season), he'd scored 46 total goals for United mainly as a starter off Ruud.
By the same point for Rashford (21 years and 3 months, after 22 games played in the PL season), he's scored 41 total goals for United with lots of appearances off the bench and mostly playing off the wing.
There's not a lot of difference.
But if we look at their respective physiques, it's easy to see that Rooney matured freakishly quickly and went on to decline just as fast.
By contrast, Rashford had a growth spurt
only one year ago (3 cm in the space of 13 months according to Jose in July 2017), and looks to be a much more natural athlete.
For goals, Rashford needs to match season-by-season:
now-2019 13
2019/20 18
2020/21 20
2021/22 34
2022/23 16
2023/24 34
2024/25 16
2025/26 19
2026/27 14
2027/28 15
2028/29 8
That takes Rashford up to the age of 31, averaging 19.4 goals per season (about 1 in every 3 games). Two seasons aside, Rooney wasn't ever at Ronaldo/Messi numbers.
That's not a super high average considering Rashford's decline is likely to come later that Rooney's.
I don't want to get into the debate about whether he'll be as good a player as Rooney, but goals-wise he's off to a brilliant start and the total is achievable with a realistic amount of luck.
A big factor could be wrenching penalty duty away from Pogba. Rooney got 27 for United. That's a huge number.
