The South African winger, described by coach Gregg Berhalter as the “Energizer Bunny” as he never stops running, netted a fine opener for Fire for his third goal in as many games in what was his first start in Major League Soccer.
Lewandowski scored the winner from the penalty spot after City had equalised, and it was another eye-catching performance from former TS Galaxy star Dithejane, who also has recent goals against Inter Miami and Mexican side Cruz Azul, against whom he scored twice.
Dithejane now has 17 appearances for Fire (five starts) and provided four goals and one assist.
"The vibes are great, every player wants to win. Our mentality is always the same," Dithejane said. "It is so special for me. I have been working hard in training, I want to score goals and make the team win.
"We told ourselves we have a lot of games coming up, we have to win those. It is all in the mind, our mentality has to be to always win.
"(Lewandowski) has been helping me with finishing, how to get into space and relax in the box. That is how we learn from legends."
Dithejane, who has previously played for Bafana Bafana at the 2025 COSAFA Cup, should be in the thoughts of whoever the incoming national team coach is ahead of the 2027 Africa Cup of Nations qualifiers next month, especially as he can cover both right wing-back and wing.
With Khuliso Mudau facing a long-term injury following the Achilles problem he picked up against Marumo Gallants on Wednesday, Dithejane could offer an attacking solution in that position.
The matches he played at the COSAFA Cup were at right-back.
