I think jA has played well since Christmas needed someone ahead of him so has improved with cox thereOf those thus far - no he hasn't got the best out of Rankine, Harper and Aitchison
Only the last two games has JA really starting to live up to his billing
Rankine has been repressed in his attacking instincts a lot IMO
Harper hasn't played much in his proper position and like Rankine gets asked to turn round and pass it rather than get the ball in early
All that being said:
Cox has improved very recently, in part thanks to Cooper, in part to GC
Cole and Diabate I agree he has impoved also
Rankine returning to fitness and have been impressed the last couple of games
Harper is only in his first proper league one season think there is a good player if he can stay injury free
Thought he was superb against Barnsley
That’s just my thoughts and opinion
