I dont think hes been a main stay at all, he took a couple of years to establish himself there and definitely went through periods where he has been out of the team because he wasn't trusted, hes had his problems with injury of course and its a high bar admittedly at CIty and Pep likes Hybrid players - which has worked for him.
Im always amazed when people think stepping out into midfield in new for him - he was doing it here. I actually think hes a bit late to the party at it at City, with his ability he should have been doing it more and for a longer time ago. I actually think he is a better deep lying midfielder then he is a centre half (thought that when he was here) - hes an average but competent defender - but his skills are ball at feet - that makes him different and a type of hybrid player Pep aims for.
But hybrid or inverted defender thing isnt new, in fact most modern systems are developing toward it and i think people are just noticing it more - even Mordor are playing TAA as a deep lying playmaker.
Im not necessarily criticing Stones, i just thought when he left here he had a higher ceiling in terms of impact and performance to become a real leader and a great player - hes a very good player. People will talk about what hes won - but i dont mush integrity or worth on Citys trophies personally - ive given my reasons a lot on here as to why.
I think Brantnthwaite is better. Hes twice the defender and equally as composed with ball at feet and his technique and vision are excellent, i think hes a more impactful player on the game. Hes a generational talent.
