The Chicago Fire have traded David Accam to the Philadelphia Union in a major trade at the MLS SuperDraft, according to multiple sources with knowledge of the move.

The Fire will receive in excess of $1 million in allocation money split between general and targeted allocation funds, sources said.

Accam has scored 33 goals with 15 assists in the past three seasons in MLS. The 27-year-old Ghanaian winger is coming off of a career year in which he scored 14 goals with eight assists.

The Fire had been nearing a new deal with Accam, whose contract is set to expire at the end of the season.

Accam gives Philadelphia one of its first major moves in this offseason and immediately upgrades the Union's attacking corps. Philadelphia has needed more attacking talent in recent years. American forward CJ Sapong scored 16 goals last season, but no other Union player had more than seven goals.

The move comes as somewhat of a shock for Chicago, which loses one of its most dangerous attacking players. The Fire do have MLS Golden Boot winner Nemanja Nikolic up top. Nikolic scored 24 goals last season in his first year in MLS.
