He's 19 years old people, what striker is fully developed at this age? He's no different from Mbappe whom many have been screaming we should sign. The thing about hold up play is that it's something he can learn, and can develop his body to adapt to, but you can't teach that natural instinctive movement that he has, his finishing is also good even though he missed a lot of easy chances yesterday, but he hasn't been playing regularly especially up top, so, it's not unexpected that his finishing & end product was generally not clutch. In my opinion, he's a special and should develop into a fine striker for us in the future.
