Third-division club Alemannia Aachen has had 19-year-old US striker Adem Sipic on trial since the middle of the week. Sipic, who plays for the development team of MLS club Nashville SC, will train with the German club for an indefinite period, giving him an opportunity for evaluation by the club's decision-makers. Although he has been included in the professional squad multiple times, Sipic has not yet made an appearance in the top American league.
