Gutter Boy
Tim Sherwood
He is currently better than Dier and close to, or perhaps even better than, Fazio.
Dier is 6 years younger than him, yet only in positioning and strength does Reid exceed him (things Dier will gain rapidly as he matures).
Reid is nowhere near Fazio's level IMO. He's quite comparable with Kaboul at the moment, except maybe fitter and a stronger character than YK.
