The first-grade Yass Redbacks should be feeling anything but secure after the reserve team applied the blowtorch with a strong win at the weekend.
As a result of the side's 3-1 victory over Gungahlin United and the poor display from the top side, coach Gary Lennon has put his first 11 on notice.
The first-graders, who are playing in division seven, were on the wrong end of a 3-1 result and Lennon said further complacency would not be tolerated.
"After their 7-2 win in the first round, and with their early goal on the weekend, they started thinking they'd wipe the floor with that team, they were just too confident," he said.
"I'll give the same team another chance because I think they got the reality check they needed but there will be changes if they play like that again next week."
Lennon told the Tribune the second-grade side (which plays in division eight) has "at least six players that could slot in tomorrow and wouldn't miss a beat".
"I mean I could sit them on the bench [for first-grade] but I'd rather have them playing regularly," he said.
First-graders Cameron Betts and Ryan Wing can breathe a little easier after they were specially mentioned by the coach for their strong early form.
"Without those two we'd be struggling," Lennon explained.
"They hold everything together; they're stalwarts in the middle for us."
Both teams now have a win and loss from their first two games and face perennial contenders ANU FC at home this weekend.
"ANU will be tough; they beat Gungahlin so we'll need to sort a few things out at training."
Lennon revealed the first and second-graders often face off against each other in ball work sessions at training to give the reserves a chance to step up and push the first team.
The women's Redbacks team suffered a 3-0 loss to Narrabundah on Sunday and will be looking to bounce back when they play Belsouth at Walker Park on Sunday at 2pm.
The first and second-grade Redbacks take on ANU FC at Walker Park on Saturday at 3pm and 1pm respectively.
