[6] His combination with Mohammad Abdullah worked superbly for Arambagh KS as they finished the premier league season in sixth position.

Nonetheless, it was another disappointing season for him, scoring only a single goal in 17 league appearance, and in turn losing his place in the senior national team.

On 10 December 2020, Jafar joined Dhaka giants Mohammedan SC, from Saif Sporting Club for a transfer fee of Tk 1.5 lakh.

He led his team to a stunning 4–3 win overcoming three goals deficit at the break against India U18 with a superb brace both coming from headers.

Since making his top tier debut for Arambagh KS in 2016 domestic season, he has been considered to hold a bright future for Bangladesh football.
