Nyongo recently returned to the side when they lost 1-0 in their final fixture of 2017 away to Cape Town City, after missing six games due to a kidney issue he picked up in September.
During his time out, Usuthu managed just one win, four draws and one defeat, which currently sees them in 12th place on the log, with just 15 points from 13 games.
The 22-year-old defender is now fully focussed on helping the team turn their fortunes around in order to ensure they retain their PSL status come the end of the season.
“The most important thing for me is to help the club retain its PSL status this season,” Nyongo told his club’s website.
“Unfortunately, I could not play in the Telkom Knockout Cup because I was out nursing an injury, but we will participate in the Nedbank Cup next year.
“I just need to stay injury free so that I can help my team achieve its objectives by doing well in both [Absa Premiership and Nedbank Cup] competitions.
“We have done relatively well at home in the league, but we need to improve our away form. There’s still a long way to go and we just need to keep pushing for positive results.”
The Old Mutual Academy graduate also reserved praise for coach Cavin Johnson, who took over the reins at the start of the current campaign.
“We are fortunate to have a great coach like Cavin Johnson, who is very supportive and helpful,” he added.
“He makes sure everyone in the team feels important. He tells you where you need to improve your game in order to become a better footballer.”
