The former Dwarfs striker has started training his new side Accra Hearts of Oak
The Phobians in an attempt to strengthen their attacking force for the 2016-17 season signed the youngster on a three-year deal.
Although, Lukeman signed for the club about two weeks ago, he has started training on Wednesday ahead of their G6 final showdown against Aduana Stars on Sunday.
Lukeman emerged as the top scorer of the GN Division One League in the 2014-15 season to help Dwarfs secure promotion back into the Ghana Premier league last season.
However, he struggled to replicate the same form in the topflight division last and had to wait until the latter part of the season to display the form that made him fearsome in the second-tier league.
