The 28-year-old left-back is training at All Stars under their new coach, ex-Bafana Bafana star David Kannemeyer.
Jenniker previously tried his luck at Highlands Park and Santos after leaving Ajax in August 2016, having only managed 11 starts in his last two years at Ikamva.
“Aidan is currently the only so called ‘PSL player’ in my group,” Kannemeyer tells KickOff.com. “Some are familiar faces and others are new.
“If they want to get a regular position in the team, then they should show me. It’s totally up to them. Grab it with both hands, show me how serious you are - that’s my message to them."
Kannemeyer, a five-time PSL winner as a player with Kaizer Chiefs (2003/4), Mamelodi Sundowns (2005-2007) and SuperSport United (2008-2010), is enjoying the early days of being in the hotseat.
“It’s good to be back,” says Kannemeyer. “We’ve had light sessions and this will progress for the rest of the week. But Monday, God willing, the hard work starts.”
