The Queens Park Rangers striker has fond memories of the Croat.
Indeed, the QPR forward feels the 31-year-old was not given enough credit for some of the things he achieved at Loftus Road, as well as his form in training.
The Croat did contribute with a remarkable free-kick or two and has, generally, enjoyed a fine career.
That's why Austin feels there has been no better player - at QPR or otherwise - he has worked with during his time in football.
Austin is quoted as saying by Sky Sports: "Niko Kranjcar. I don't think he got enough credit for some of the stuff he did in training and in games. He was class."
It's interesting to see Austin single out a Harry Redknapp favourite from his time at QPR (Redknapp took Kranjcar to Spurs and Portsmouth, as well). Generally, of course, 'Arry wasn't exactly known for signing quality players for the R's.
Most of the former manager's recruits were overpaid and past their sell by date.
Kranjcar, meanwhile, didn't feature all that much due to fitness, anyway. But at least Redknapp's time with the club left one positive legacy outside of a promotion that was soon cancelled out by relegation.
