Ones to watch
Neil Warnock said that he couldn't think of a better player he has ever managed than McNair, which is saying something when it comes from such an experienced manager as Warnock.
A move to centre-back this season has proved to be a brilliant move for the Northern Irishman, with him being one of the best this season in the division. Expect him to be a nuisance for the Birmingham attack.
Arriving from Spain in the summer, Sanchez is getting to grips with life in England but is adapting well.
One goal and three assists already this season, his pace and trickery on the right-hand side has proved beneficial for the Blues on the counter-attack, and Warnock is for sure going to want to keep him contained.
