Grosskreutz and Reus were both players from Dortmund's youth academy.
However, they were both unable to break into the first team and ended up leaving for Red White Allen.
Red White Allen was the team from Allen Town, a small coal mining town about 60 kilometers northeast of Dortmund. The club had very close youth academy ties with Dortmund.
They had always played in the regional leagues. It was with the help of players like Grosskreutz and Reus, from Dortmund's youth academy, that they were promoted to the 2nd Bundesliga. They finished 10th in the 2nd Bundesliga last season, successfully avoiding relegation.
It was thanks to their outstanding performances in the 2nd Bundesliga that the two players were able to return to Dortmund.
Grosskreutz's return had been planned for some time.
But Reus's signing was a last-minute decision by Klopp.
