You just don't understand football at all.What are you talking about
Your trying to justify Chrisās Rigg is a once in a generation talent, justifying him being spoke of in the same breath as Jude, Messi and Rooney and trying to defend that by saying heās not grown yet so letās compare him to Phil foden, when thatās rubbished heās now āin a totally different roleā wtaf!!
Just accept your going overboard mate, itās really not that difficult.
Playing wide, as Foden did for City as a kid is a completely different task to playing in centre midfield. As a wide player you tend to be one on one with a full back. Playing CM there is half a dozen players all battling for the same ball. Less time, less space, more competitive. It's a far harder and robust role.
Chris Rigg is playing in the hardest position as a slight 17 year old kid.
