Alex Smithies 8
Made a world-class save to stop Ravel Morrison scoring. Also gathered a number of tricky crosses, too.
Perry Ng 7
Uncharacteristically dicey in possession early on and came off second best in a couple of tackles, too. But really improved. Put a lovely ball in for Ikpeazu.
Aden Flint 7
A solid outing, defensively, from the big centre-back. Misplaced the odd pass, though.
Mark McGuinness 5
Cards on the table, he wasn't at his best. Gave the ball away far too often and was a little sloppy defensively.
Cody Drameh 7
Didn't have as much joy as usual but still looked threatening at times. A few crosses needed to beat the first man, though.
Ryan Wintle 7
Does make a difference at the base of this midfield. Cardiff needed him to have his wits about him, and his pace, against the Rams.
Joe Ralls 7
Tried to bring an air of calm to Cardiff's midfield and grew into the match as it went on. Struck the bar with a stunning effort.
Tommy Doyle 8 (star man)
Another whose influence grew throughout the night. Sent one monster effort crashing into the bar from 30 yards and covered every blade of grass.
Joel Bagan 6
Festy Ebosele had the better of him with his incredible pace. Put in a couple of nice crosses in attack, though.
Jordan Hugill 7
Looked the most likely to give Cardiff a platform and toiled away. Sent a first half header narrowly over the bar.
Isaak Davies 6
Struggled with Derby's physicality and even when he was put in space he struggled to exploit it. Booked early on, too.
Subs
Uche Ikpeazu (on for Hugill 66) 8 - Really put himself about and caused Rams a problem. Took his chance excellently.
Mark Harris (on for Davies 71) 6 - Stretched the Derby defence late on. A decent outing.
Alfie Doughty (on for Bagan 72) 6 - Did well enough replacing Bagan, but booked for a poor challenge.
