Well for me his skillset is similar to Robben, apart that Madueke can do it with both legs (not saying hes gonna be as succesful). You know what hes gonna do, still its hard to stop.
The video is also against Ajax. They know exactly what hes capable off. Still he makes it look easy after being out for 2 months. Thats why I know he can be great. Hes out for 3 months, doesnt need any rhythm and scores 2 against clubs like Ajax or AC milan just by surplus of talent.
I honestly feel we wouldve sold him for 80 million if it wasnt for the injuries. I guess thats why you get half price.
