The latest centre-back to roll off the Cobham production line is Tayo Subuloye. Levi Colwill and Josh Acheampong are in Xabi Alonso's first-team squad while Marc Guehi, Fikayo Tomori and Trevoh Chalobah are among the former Chelsea academy products to be excelling elsewhere. Now Subuloye, 18, is knocking on the door of the first team, having trained in Alonso's group before the 3-0 defeat to Brentford.
