1. Cassio (Adelaide United)

For sheer service, consistency and quality, there's little doubting Cassio has been the A-League's best performing Brazilian import. In fact, the nuggety left-back enjoys the A-League and Adelaide so much he's set to get his Australian citizenship.

The 31-year-old pocket rocket, who loves to get forward down the left flank, has been with the Reds since 2007, winning the Club Champion & Player’s Player of the Year awards in his debut season. Cassio rediscovered his stellar debut season form during the 2010-11 campaign when he provided six assists before winning the Club Champion award again, as well as being named in the A-League All-Star Team.

Rio de Janiero-born Cassio is a solid defender with a genuine attacking threat, while he has also embraced his club which is everything you could want from an import.
