Seb Ryall is ready to step into a key defensive role at the club following the departure of one man in particular.
The 21-year old has his eyes firmly on the central defensive vacancy left by Simon Colosimo who joined new A-League club Melbourne Heart during the off-season.
Ryall, who has overcome some tough times recently having charges against him dropped for engaging in a sex act with a minor, is now ready to put all that behind him and become a major player for the reigning champions.
''It's a good opportunity now that he [Colosimo] is gone and I feel like I've done really well this pre-season,'' Ryall said. ''Stephan (Keller) played as the right-sided central defender last year and that often meant he was closest defender to me, so we've already learnt how to play together.
''I feel most comfortable playing at centre-back and I'd like to have it cemented before we come up for round one. I much prefer it to playing right-back - I don't really like right-back.''
