I think one of the issues with several of these type of talents, Gore, Isak, Mejbri, is that they are rarely ready to play for a top team in midfield before 24-25 year old. Look at players like Mac Allister, Odegaard and Modric. We all knew of them from an early age, but they did not play regular football at «great» teams at the highest level before 24 years of age. The same was the case for Bruno, Carrick, Fernandinho, Henderson, Winjaldum, Fabinho, Gundogan, Yaya etc. Even KdB.
There is a few exceptions. Players that are both physically and mentally very mature at an early age. But I think we overestimate how many of them there is and the likelyhood of one of our talents being ready at an early age. And to fullfil their potential they need to play regular football at a decent, competetive level from 20 to 24 years old.
