Ciro Immobile, Dortmund's nomadic striker, has returned to his former club Torino on loan, and appears to have rediscovered some form after two difficult years.
This is the second time the Bundesliga runners-up have loaned out the 26-year-old, the first time being to Sevilla after a disappointing first season in Germany.
The player also underperformed at the Spanish club, and after a serious facial injury found himself back in Italy, on loan to the side where he first caught the eye of larger European clubs by scoring 22 Serie A goals in only 33 appearances.
Torino have the option to buy the player back for a reported €11m.
Immobile has found the net on five occasions and provided two assists in 11 starts for the club and in an interview at a recent sponsor event, he suggested that the move would suit him.
"I thank Torino, the coach and all the team for helping me get back into the Nazionale before the derby with Juventus, but then unfortunately I had this injury,” he said, referring to the hamstring injury that has had him sidelined for the past seven matches.
"Now there is an important game coming up for me and I will try to give my best," he continued.
"As for my future, I can only say that I am happy at Torino, but what counts now is to end the season on a high.
"Along with [Andrea] Belotti we’ve done great things together and Josef Martinez is also doing well.
"Paradoxically, the team has almost done better without me," he added.
The Turin club finished eighth and seventh in the last two Serie A seasons and are currently lying in 11th with the possibility of ending the season in 10th, depending on this upcoming weekend's fixtures.
