Cardiff probably have the best pool of centre backs; Manga, Connolly, Morrison, Bamba, in the division. Rate them in order

Morrison and Bamba tied for top, Manga, Cononley, Peltier if needed

Edit: on second thoughts, it's so hard to choose between Bamba, Morrison and Manga! Manga has been very good this past month, Morrison has been great all season and Bamba is Bamba. Tough choice.

I think Bruno Manga is a cut above all of them. He is premiership class in my opinion and we were very lucky to keep him.
Morrison and Bamba are very solid championship defenders, Connolly is decent back up but i would play Lee Peltier ahead of him at centre back in all honesty.

Its probably Warnocks hardest decision with this squad in regards of who to pair together

If you asked me at the start of the season it would have been very different however, if your asking me in order of who I would play this season.

Morrison
Manga
Bamba
Connelly
