I'd have Whitts at or near the top in any list of either the best technical or most skilful City players I've seen - Alan Curtis would be another one on both lists, while another ex Jack Jason Bowen had a lot of talent and, going back a long way and sticking the ex Jack theme, Barrie Jones was a skilful performer.
More recently, I always though Anthony Pilkington was a good technical player.
Although I wasn't a great fan of his while he was at Cardiff, Robin Friday would be up there as well and Adrian Alston had a taste for the unusual which revealed him as a skilled performer.
Kimbo was a very good technical player as well and Mats Daehli also deserves a mention as well.
Rambo would be in any list of skilful and/or technical players as well.
Danny Gabbidon and Mark Delaney were also good enough technically not to get found out in the Premier League.
