Gambia and SK Lierse embattled striker, Assan Jatta, commonly known as Bierhoff, has left American First Division side, FC Dallas, after a ten-day unsuccessful trial.

The MLS giants have passed up the chance to sign the 24-year-old forward after his failure to impress in the eyes of the club's coaching staff.

"Assan Jatta's trial was unsuccessful and he's gone," a terse statement posted on the club's website revealed.

Assan Jatta joined  Belgium side, SK Lierse, in 2007 alongside his comrade Mustapha Jarju from Steve Biko. But the athletic striker's failure to adapt to life at SK Lierse saw him spend the better part of his two-year contract with another second division side, K.F.C. Verbroedering Geel

With his one-year loan spell with Geel expiring last season, it seems SK Lierse are in no mood to keep the injury-plagued forward who has 12 caps to his name.
