Don't want it to sound like I'm bigging him up too much, it'd more be taking advantage of a market opportunity if Liverpool were practically giving him away for free to clear his wages off their books.
He's a bit of a meme but he's also a complete chaos merchant and while his numbers backed off a bit this year, under Klopp he was the 100 percentiler when it came to shots per 90 and his combination of pace and power is right up there. His stock is low but I could see Darwin getting 20 goals in the right environment - although clearly United has not been the optimal environment for a LOT of players so how likely is it that it would be for Darwin.
By the way, his numbers are not comparable to Hojlunds at all. He's got 16 goals and 10 assists in 35.3 90s in the league, while Hojlund has 14 goals and 2 assists in 46.2 games. That's a difference of .74 goal contributions/90 to .35/90. Darwin's expected figures are even higher.
