During the past month there has been plenty of movement in the Official AFL Player Ratings, brought to you by Vero.

Adelaide's Patrick Dangerfield, who started the season at No. 15, has surged to No. 3, while Essendon skipper Jobe Watson, who was No. 8 after round six, has charged up to No. 4.

In round 11 some of the highest-rated players will be going head-to-head, while many players have the chance to dramatically improve their ratings with good performances.

On the flipside, a number of players need to be near their best or they will slide down the pecking order when the updated ratings are released on Tuesday, June 11.

KEY MATCH-UPS THIS WEEKEND
The clash between Adelaide and the Sydney Swans at AAMI Stadium on Saturday evening will pit the No. 2 and No. 3 players in the competition, Josh Kennedy and Patrick Dangerfield, against each other.

The game will also feature Crows midfielder Richard Douglas, who has amassed the second-highest tally of player ratings points so far this season, behind only Gold Coast skipper Gary Ablett.

PLAYERS ON THE UP
North Melbourne forward Lindsay Thomas, who will be a key player in Saturday night's game against Gold Coast at Metricon Stadium, has climbed 94 places on the player ratings ladder this season. Having started the season at No. 191, he now sits inside the top 100.

PLAYERS WHO NEED TO LIFT
Melbourne midfielder Colin Sylvia, who is set to return to the Demons' side for the Queen's Birthday match against Collingwood after serving a three-match suspension, has been one of the season's biggest sliders. Sylvia began the year at No. 38, but has slid to No. 86 after 10 rounds.
