Thomas Roberts is travelling for his second such stint at the German champions, and this time he will be accompanied by fellow midfielder Brandon Servania.
Dallas defender Chris Richards, 18, is currently on loan at Bayern after initially spending 10 days with the German club in April.
Seventeen-year-old Roberts was with Richards on that trip and, having scored eight goals in 18 appearances for FC Dallas U19s last season, the Arkansas native is set for another spell in Bavaria.
Servania, meanwhile, has played 17 games since May while on loan at United Soccer League side the Tulsa Roughnecks. Like Roberts, the 19-year-old has been capped by the United States at U18 level, and he will now get to test himself at the home of the record German champions.
Both homegrown players will be hoping to emulate Richards, who impressed enough during his first visit to Bayern to be snapped up on loan in July. The Alabama native has since scored once in six starts for Bayern’s U19 team this season.
The latest visit by FC Dallas players is part of Bayern’s partnership with the American outfit, which has seen the two clubs trade coaching expertise as well as personnel.
USMNT youth internationals Bryan Reynolds, Reggie Cannon and Paxton Pomykal also spent a short time at Bayern’s training centre last December.
