Ashley Cole has warned Arsenal that Bukayo Saka will never reach the levels of a 'top, top player' if he is continually 'used and abused' in a range of different positions.
Saka endured an off-night at Stamford Bridge on Wednesday in a right wing-back role and Cole, while full of praise for the 'fearless' teenager, is wary of the downside too much adaptability brings.
Arsenal went on to win the game thanks to an error by Jorginho gifting Emile Smith Rowe a tap-in but Saka's below-par display is an issue for boss Mikel Arteta.
