With coach Alistair Edwards sacked on Monday and caretaker Kenny Lowe due to take charge against for the round 11 match against Adelaide United at nib Stadium, the re-signing of Sidnei after 10 games was pushed through by owner Tony Sage and chief executive Jason Brewer.
A deal was already on the table before the 27 year-old scored a contender for goal of the season from long-range as part of a brace in Glory’s 4-2 win over Wellington Phoenix in Round 9.
Having succumbed to a hamstring strain after that game, Sidnei was badly missed in the Round 10 2-0 loss to Melbourne Victory - a match that sparked the player revolt that led to Edwards's sacking.
Sidnei, who also set up another of Glory’s goals against Phoenix, is almost certain to miss out against the Reds as he continues his recovery.
'I’m pleased to have had a good start to the season and I am enjoying my role at the club," he said. "I am glad to be staying here and I want to be a part of something important at this club.
'Scoring the two goals against Wellington was great for me and the first one gave me real satisfaction. Those are good moments for a footballer.
'I also love to set them up and that is a big part of my job. Hopefully I will continue to play my part and keep getting better as the season goes along."
Sage believes Sidnei will continue to hit the target as well as create opportunities: 'His goal against Wellington showed what he is about and he could have had a couple more than this year.
'We like what we have seen from him. He’s been one of the top five players in the A-League so far this season but hasn’t received the credit he deserves."
