I never watched him in youth level, but you are not the only one who do not rate him from that period. But he won Academy player of the year award.
It is hard to tell because he is so versatile. Some games he played really up for Swansea like LW and I did not like that. If he plays that here sometimes I would moan just like with Mount.
His style is similar to Modric I would say. But Conor is 10cm taller and more stronger. If Modric and Gerrard had love child that would be Conor. So CM is his best position imo.
For example we played 4-3-3 last game with Kante and Kovacic and this is his best position because he can play to his strengths both offensively and defensively.
He has everything that Mount has but with dribbling, vision, creativity and physicality. Good at tackles as well. Not sure I can find any significant weaknesses to his game.
