Answer
The answer is Chelsea F.C., an English Premier League club based in London. Despite being signed by Chelsea in 2012, Thorgan never made a competitive appearance for the team. Instead, he was loaned out to several other clubs during his time at Chelsea, including Borussia Mönchengladbach, Anderlecht, and Zulte Waregem, before eventually securing a permanent move to Borussia Dortmund in 2017.
