The People's Team are propping up the NFD standings with 18 points from 25 games - seven points behind nearest sides Magesi and FC Cape Town.
De Nobrega accepts the 2002 PSL champions are in trouble but refuses to give up hope.
"Things are more difficult now," De Nobrega told snl24.com/kickoff after a 2-0 loss to Real Kings this past weekend.
"We haven't won any matches, so we haven't collected any maximum points."
He added: "Mathematically it's still possible. We can't look too far ahead, we must look as far as our next match. We must always have hope because if we don't what will be the point of playing our next game?"
Santos midfielder Ruzaigh Gamildien likewise stressed the need to stay positive when asked about his future. The former Ajax Cape Town man joined the second-tier outfit in February on a short-term deal.
“Look I’m here now and hoping to help the club,” Gamildien said. “It’s really a very difficult situation to be in but we need to remain positive.
“In terms of my personal career I just need to play regularly. I have some options that I’m pondering. There are three potential clubs but that’s all I can say.”
