Issahaku opened the scoring in the 36th minute with a trademark left-footed strike after cutting in from the right flank.
The former Steadfast FC winger doubled Sporting’s lead in the second half with another fine strike after making light work of his marker.
The highly-rated teenager completed his hat-trick in the 79th minute, sandwiched by goals from Ribeiro and Fernandes, as Sporting recorded a comfortable win at home.
Issahaku’s performances could go a long way for Sporting’s young side to help their development since joining the Portuguese giants.
He has enjoyed limited playing time for Sporting’s senior team this season, often coming on as a second-half substitute.
The teenager made his UEFA Champions League debut in October as Sporting Lisbon lost to Olympique Marseille.
He has since made cameo appearances for the Portuguese side and has played 10 games for the club in all competitions so far.
However, his recent performances could boost his chances of getting more playing time for Sporting’s senior team.
