Jabaar, 18, has developed a reputation as one of the most promising talents in Nigeria since bursting onto the scene during their U-17 African Cup of Nations campaign - where he netted two goals in four games as they finished fourth.
The teenager then went on to represent his nation in the U-17 FIFA World Cup in Brazil and featured in every game before The Netherlands knocked them out in the round of 16.
Nigerian football expert Tosin Holmes tells snl24.com/kickoff that the DStv Premiership have acquired a 'gem' as they continue to secure talent across the continent.
"He's great player, pace to burn, move between the line, great passing range and played at the U-17 World Cup, he's destined for big things, Stellies have signed a real gem," he said.
Steve Barkers's side will be looking to move up from 11th in the table when they host high-flying Golden Arrows at the Danie Craven Stadium on Friday afternoon (17h00).
