Warnock doesn't see Coulson as a left back. He sees him as an attacking player. I have him taped saying that to press reporters on a pre-match press conference during lockdown.
Am I right in saying the only game Coulson has started in whilst Warnock's been here was Hull away, and he played on the wing?
I've found it surprising really that he hasn't given him more opportunities. He's saying he doesn't see him as a left-back but he hasn't actually seen him playing in that role, although I appreciate he may be basing that on what he's seen in training.
