I think he is probably referring to Haaland and its a fair point. Haaland is 7 years younger, doesn't have a poor injury record and also has a sell on fee. On the flip side he's never done it in the prem and hasn't sustained his form for a number of years as Kane has.
From a purely business point of view, you'd think Haaland would be the better option on this basis.
Can't be arsed to write a long post about this again, but essentially, I don't see any chance of us ever getting Haaland when we won't be willing to pay the huge numbers in wages, sign-on fees and bonuses that clubs like Real or Barcelona give without even blinking. Even if Haaland wants us, Raiola will convince him to join the club that is best for his own pocket.
