Carlton forward Charlie Curnow has failed to fire so far in 2019, and former St Kilda forward Nick Riewoldt has some advice for the 22-year-old.

Curnow has been battling a knee injury over the course of the season so far, but has just two goals from four games for the Blues, and is only averaging 4.2 marks per game.

Riewoldt wants Curnow to tinker with his game a little, and believes the forward should focus more on playing as a forward, instead of just an athlete.

“He’s struggling. We did the top 10 key forwards by the end of the year in the pre-season and I didn’t have him in there just because I like his athletic capabilities, he’s clearly a talented kid, but we just haven’t seen it yet,” Riewoldt told SEN Breakfast.

“I’ve seen him play a few times this year and the thing that really sort of stands out is that he is so gifted athletically that I think at times he’s playing too much athletics on the field.

“What I mean by that is the actual leading patterns, staying a kick or a kick and a half away or just being in positions constantly where you can draw the footy, rather than just relying on being a great athlete all of the time.

“They’re the layers to his game that I think are missing at the moment.”

Despite Riewoldt believing in the Blues’ progress this season, he did say he was “disappointed” in their efforts on Sunday during their 58-point loss to North Melbourne.
