Why do we need a wide attacker?
The positioning and defensive responsibility McNeil and Iwobi have had since Dyche came in are similar to wing backs in other teams. It is more defensive than what we have seen from Chilwell, Peresic, Porro, James etc. Dyche does not play with wide attackers. Never has.
He signed and had success with Aaron Lennon when he now longer had offensive output. He signed Maxwel Cornet that had impressed as a winger and wing-back for Lyon, but mostly used him as a centre forward.
