Non-penalty goals per 90 in their PL seasons:
Toney:
0.22
0.43
0.25
Hojlund:
0.42
And lest you think Hojlund benefitted from playing for a better attacking team, our xG last season was on par with Brentford's last two seasons. 56.5 versus 58.2 & 56.3.
Far from Toney being some PL-proven guarantee of goals that Hojlund isn't, Hojlund almost exactly matched Toney's best rate of returns in the PL in his very first attempt.
With Hojlund being being more likely to improve at 21 than Toney at 28, there's quite a strong chance that Hojund is simply a better goalscorer than Toney from here forward.
Penalties and minutes seriously warp some people's perception of his goal threat. If you're looking to add a more reliable source of goals, Toney simply isn't the guy.
