Yes definitely behind Ayala last season. If you're looking for a classy defender relatively cheap Ayala will probably be available this window for around £10m. Him and Karanka seem to have a bit of a personality clash, nothing major but it has lead to Chambers coming into the team (although he has stayed there on merit).
I like Keane, not so keen on Dunk. Dunk seems to be a bit of a hot head, reasonably regular sending offs aren't great to see, especially in a league that is so physical. Keane is a classy player who I do like, not as much as Gibson but I do like him. Much calmer player than Dunk and has a height advantage over Gibson I believe.
Him and Chambers seem to have a bit of a telepathic relationship with each other, which is a brilliant thing to see between a partnership. Like I said in another post, I expect him to go to a massive team when he does leave (which he will), do yeah you probably have missed the boat on both him and Keane. I've never noticed him being overly slow, usually keeps up with most strikers relatively easily, but I will try to look out for it.
