Madueke was by all reports an arteta signing not a berta signing
He's shit and people think he's going to magically step up a level, he's a few month off saka in age turning 25 soon, he isn't some prospect - Competent backup I hear? What is competence? Dribbling past one or two players? His end product is shocking and his defensive work is equally poor. You take 10-15m more and could have got Semenyo, Cunha, Mbuemo etc.
Let's not pretend Kai was some stroke of genius too - He was brought in to replace xhaka in midfield and then when the rice-ode-xhaka stuff wasn't working, he got another life at CF as jesus was perpetually injured
Saying that only one other striker in 3 years moved that's better than Kai is equally laughable and delusional - Joao Pedro, Ekitike, Alvarez (Who i don't particularly rate but a better forward than Kai for sure) among quite a few others
Injury prone, inconsistent, unreliable finisher - at 300k a week not even sure we'd recoup much money for him
