Former Sydney premiership player Jude Bolton has revealed his top five most improved players in the AFL this season, in a column for ESPN.com.au.

With the season now over a third of the way through, teams have established themselves and contenders while others have shown themselves to be pretenders, and the same goes for some of the stars of the game.

Fremantle's Nat Fyfe, Melbourne's Max Gawn and Western Bulldogs' Jackson Macrae have all starred throughout the season, as those three players are looking at certain All-Australian berths after eight rounds.

Some stars like Patrick Dangerfield, Tom Mitchell, Dustin Martin and Zach Merrett have all failed to fire at stages throughout the season, but many are expecting them to all find their best soon enough.

However, Bolton has come up with a list of his top five most improved players, and the full article can be seen here.

"There were huge wraps on him as a junior and now Curnow has taken some massive steps forward to regularly impact at AFL level," Bolton wrote.

"Despite the lack of supply and a poor start to the year for the young Blues outfit, Curnow has increased his averages in key areas such as disposals, contested marks and inside 50s."
